Top 5 Reasons Why Lock&Lock Fresh Stainless Steel Kimchi Container 6L Is the Best
- Zero odor and stain absorption, the hygienic power of 304 stainless steel. Unlike plastic kimchi containers that absorb odors and stains, this eliminates those issues entirely. Kimchi brine's red color won't seep in or leave odors, allowing for versatile use. One reviewer noted, "After switching from plastic to stainless steel, I can definitely feel the difference."
- 4-sided locking seal prevents kimchi brine leakage. Lock&Lock's signature 4-sided clip-style wings and thick silicone gasket enable perfect sealing. Real users mentioned "not a drop leaked even when laid on its side in the refrigerator," and many noted "the lid locks with a satisfying click."
- Transparent lid makes content checking convenient. While opaque lids require opening to see contents, the transparent lid lets you identify which kimchi is inside at a glance. One reviewer noted, "Even with multiple containers in the kimchi refrigerator, it's easy to find what I need and keeps things much more organized."
- Dome-shaped lid provides generous capacity. Compared to flat lids, the upward-curving dome shape stores more than the stated capacity. It remains hygienic as kimchi won't touch the lid even when expanding during fermentation, with reviews confirming "even when filled generously, the lid closes well."
- Lightweight with sturdy handles for easy transport. Despite the 6L capacity, it's relatively light, and sturdy handles on both sides allow safe lifting even when full. Real users noted, "Even filled with kimchi, the handles are strong enough to carry with one hand."

Who Is This Product For?
The Lock&Lock Fresh Stainless Steel Kimchi Container 6L is best suited for 2-3 person households, those needing kimjang kimchi storage, and anyone wanting hygienic containers without odor or stain concerns.
We recommend this for:
Those stressed by plastic kimchi container odors and staining. While plastic retains kimchi odors and red coloring that make it difficult to repurpose, 304 stainless steel returns to like-new condition with washing alone.
2-3 person household kimjang kimchi storage. The 6L capacity stores approximately 2 heads of cabbage while not being too large for efficient refrigerator space use. It's the perfect size for dividing kimjang portions into manageable amounts.
Those prioritizing prevention of kimchi brine leakage. The 4-sided locking seal system and silicone gasket prevent even a single drop of kimchi brine from leaking, keeping your refrigerator clean.
Those wanting convenient refrigerator organization. The transparent lid lets you identify which kimchi is inside without opening, making refrigerator management much easier.
Those wanting multipurpose use beyond kimchi. The dome-shaped lid and appropriate height make it suitable for various uses including storage, side dishes, and marinating meat.
Not Suitable For
Large family bulk kimjang storage. The 6L suits 2-3 person households; for larger families, we recommend the 7.2L or purchasing multiple containers.
Those requiring microwave use. Stainless steel cannot be used in microwaves, so if microwave heating is essential, glass or plastic containers are more appropriate.
Those wanting ultra-lightweight containers. While slightly heavier than plastic, the 6L is on the lighter side for stainless steel products. If extreme lightness is needed, consider plastic alternatives.

What Are the Pros of This Product?
Zero odor and stain absorption (approx. 119 reviews, 90%). The biggest drawbacks of plastic kimchi containers—odor and red staining—are completely eliminated. Even after kimchi use, it returns to like-new condition with washing alone, allowing for various repurposing. One reviewer noted, "I was worried about kimchi staining, but there's absolutely no discoloration and no lingering odor—very satisfied."
4-sided perfect seal (approx. 106 reviews, 80%). Lock&Lock's signature 4-sided clip-style wings and thick silicone gasket prevent even a single drop of kimchi brine from leaking. Real users mentioned "no leakage whatsoever even when laid on its side in the refrigerator," with very high satisfaction regarding sealing performance.
Transparent lid convenience (approx. 92 reviews, 70%). Unlike opaque lids, you can identify which kimchi is inside at a glance without opening, making refrigerator organization much easier. One reviewer noted, "Even with multiple containers in the kimchi refrigerator, it's easy to find what I need and keeps things neat."
304 Stainless Steel hygiene (approx. 106 reviews, 80%). Food-safe 304 stainless steel material offers excellent rust and corrosion resistance, and is safe for acidic foods like kimchi. It remains hygienic without deformation or corrosion even after long-term use.
Dome-shaped lid generosity (approx. 79 reviews, 60%). Thanks to the upward-curving dome lid, you can store more contents than flat lids, and it remains hygienic as kimchi won't touch the lid even when expanding during fermentation. One reviewer noted, "Even when filled generously with kimchi, the lid closes well."
Lightness and transport convenience (approx. 79 reviews, 60%). Despite the 6L capacity, it weighs only about 800g, relatively light, and sturdy handles on both sides allow safe lifting even when full. Real users noted, "Even filled with kimchi, the handles are strong enough to carry with one hand."
What Are the Cons of This Product?
Poor shipping packaging (approx. 21 reviews, 16%). Some reviews complained that 'shipping packaging was only a thin layer of plastic wrap, causing corner dents.' As a solution, we recommend checking immediately upon receipt and requesting an exchange if severely damaged, with recent reviews noting improved packaging.
Thin stainless steel thickness (approx. 13 reviews, 10%). Some reviews mentioned "the steel thickness was thinner than expected, which was initially surprising." However, there are no issues with use, and it's actually lighter, reducing weight burden even when filled with kimchi. As a solution, if you want thicker steel, consider premium lines.
Polishing residue cleaning required (approx. 26 reviews, 20%). Due to stainless steel manufacturing characteristics, polishing residue may remain, requiring pre-use cleaning. As a solution, mix warm water, vinegar, and dish soap in a 2:1:1 ratio, wipe with a soft sponge, then rinse. Two washes are usually sufficient.

Frequently Asked Questions (FAQ)
Where can I buy the Lock&Lock Fresh Stainless Steel Kimchi Container 6L at the best price?
Currently, Coupang Rocket Delivery offers the best price at ₩18,300 KRW. You can receive it within 1-2 days via Rocket Delivery, with additional discounts available when applying coupon codes. While also available on Naver Shopping, Coupang maintains the most stable pricing.
Does the Lock&Lock kimchi container price fluctuate significantly? When is the best time to buy?
Kimchi container prices can vary with seasons and promotions. Discount events are especially common during kimjang season (October-November) and year-end holidays, so we recommend adding it to your ‘favorites’ on the Coupang app to receive price alerts. The current ₩18,300 KRW is reasonable compared to average pricing.
How many heads of napa cabbage kimchi fit in the 6L container?
The 6L capacity holds approximately 2 medium-sized napa cabbage heads. The dome-shaped lid allows for more generous filling than the stated capacity, with 1.5-2 heads being ideal when accounting for kimchi brine. Real users frequently noted “fit 2 heads of cabbage” and “added half a head after one full head.”
Is 304 stainless steel material really safe?
Stainless steel 304 (STS304) is the most widely used safe material for food containers. Containing 8% nickel and 18% chromium, it offers excellent rust and corrosion resistance, and is safe for acidic foods like kimchi. Unlike plastic, it has virtually no odor absorption and maintains hygiene without deformation or staining even after long-term use.
Will the transparent lid crack or break?
The lid is made from ABS material, which has higher strength than regular plastic. Among 132 real user reviews, there were virtually no cases of lid damage, with over 80% noting “the lid is sturdy.” However, avoid sudden temperature changes (refrigerator → hot environment), and hand washing is recommended as dishwasher use may cause deformation.
Does the 4-sided sealing really work well? Will the brine leak?
Lock&Lock’s signature 4-sided locking mechanism combined with silicone gasket provides excellent sealing. Multiple reviews confirmed “not a single drop of kimchi brine leaked” and “fine to lay on its side in the refrigerator.” The clip-style wings lock securely in 4 directions, effectively blocking kimchi odors as well.
How do I remove polishing residue?
Due to stainless steel manufacturing characteristics, polishing residue may remain. Before first use, mix warm water, vinegar, and dish soap in a 2:1:1 ratio, wipe with a soft sponge, then rinse and dry. Real users reported “minimal residue inside, only a bit around the rim” and “two washes were sufficient.”
What are the advantages of the dome-shaped lid?
The dome-shaped lid curves upward, allowing more contents to be stored than flat lids. When kimchi ferments and expands, it won’t touch the lid, maintaining hygiene. Over 70% of reviews noted “the kimchi doesn’t touch the lid, which is great.” It’s especially effective at preventing overflow when storing kimchi with lots of brine.
Can I use it in a microwave or dishwasher?
It cannot be used in microwaves, ovens, or over direct heat. Stainless steel in microwaves can cause sparking. For dishwashers, the body is safe but the lid may deform, so hand washing is recommended. Thanks to the smooth surface, hand washing is easy anyway.
How does the 6L compare to other Lock&Lock container sizes?
Lock&Lock stainless steel kimchi containers come in four sizes: 2.5L, 4.2L, 6L, and 7.2L. The 6L is ideal for 2-3 person households storing kimjang kimchi, and is not too large for efficient refrigerator space use. We recommend 2.5L for small batches of fresh kimchi, and 7.2L for bulk kimjang storage. All sizes have identical length/width for neat stacking.
Do containers often arrive dented during shipping?
Some reviews (about 16%) complained that “shipping packaging was only a thin layer of plastic wrap, causing corner dents.” However, denting doesn’t significantly affect use, and we recommend requesting an exchange if severely damaged upon receipt. Recent reviews note improved packaging.
What are the pros and cons compared to plastic kimchi containers?
Pros: No odor or stain absorption, hygienic, high durability, premium appearance. Cons: Slightly heavier than plastic (though 6L is on the lighter side), somewhat higher price. Over 90% of real users stated “so glad I switched from plastic to stainless steel,” with the consensus being that it offers better value for long-term use.

Comparison Analysis
Lock&Lock Fresh Stainless Steel Kimchi Container 6L Strengths: The biggest advantage is the combination of capacity perfectly suited for 2-3 person households with reasonable pricing. It can generously store 2 heads of cabbage while not excessively occupying refrigerator space, making it highly practical.
Comparison with 2.5L: The 2.5L is suitable for storing small batches of fresh kimchi or green onion kimchi. The Lock&Lock 6L offers more than double the capacity with only about ₩4,600 price difference, providing better value if kimjang kimchi storage is the goal. The 2.5L is more suitable if prioritizing small side dish or storage purposes.
Comparison with 4.2L: The 4.2L stores approximately 1 head of cabbage and costs about ₩2,600 less than the 6L. For 1-2 person households, the 4.2L is sufficient, but it requires the inconvenience of dividing batches during kimjang season. For 2-3 person families, choosing the 6L is recommended.
Comparison with 7.2L: The 7.2L is for large family kimjang use, storing 2.5 heads of cabbage and costing about ₩2,400 more than the 6L. If you have a family of 4 or more or need to store bulk kimjang kimchi, the 7.2L is suitable, but if refrigerator space is limited, purchasing two 6L containers is also a good choice.
Other Good Alternatives
For small batches of fresh kimchi or side dish storage, we recommend the Lock&Lock 2.5L. It costs about ₩17,000, is more affordable, and the lower height makes it easy to stack multiple containers on refrigerator shelves. Suitable for households that frequently make small batches of green onion kimchi or radish kimchi.
For large family bulk kimjang storage, we recommend the Lock&Lock 7.2L. It costs about ₩24,000, stores 2.5 heads of cabbage, and reduces the inconvenience of dividing into multiple containers during kimjang season. Suitable for families of 4 or more.
How to Install and Use It?
Based on analysis of reviews and official instructions, you can easily use it by following these steps:
Pre-Use Cleaning (Required)
Due to stainless steel manufacturing characteristics, polishing residue may remain, so pre-use cleaning is essential.
- Prepare cleaning solution: Mix warm water, vinegar, and dish soap in a 2:1:1 ratio.
- Use soft sponge: Apply the mixture to a soft sponge and thoroughly wipe the interior and rim. Pay special attention to the rolled rim area where polishing residue is most common.
- Rinse with water: Rinse multiple times with clean water to remove all detergent.
- Complete drying: Remove all moisture and dry in a dry location.
Real users reported “minimal residue inside, only a bit around the rim” and “two washes were sufficient.”
Filling and Storing Kimchi
- Fill appropriate amount: Fill the 6L container to about 80% capacity (approximately 4.8L). The dome-shaped lid provides extra space even with lots of brine.
- Close lid: Press down the 4-sided clip-style wings in sequence to lock. A ‘click’ sound indicates complete sealing.
- Refrigerator storage: Store in refrigerator or kimchi refrigerator. The transparent lid makes content checking easy.
Cleaning and Maintenance
- Regular cleaning: After use, wash with dish soap, remove moisture, and dry. Thanks to the smooth surface, hand washing is simple.
- For long-term stains: Soaking in vinegar water before washing maintains the original shine.
- Silicone gasket care: The silicone gasket is removable, so periodically removing it for cleaning prevents odor buildup.
Usage Tips
- Avoid sudden temperature changes: Immediately immersing in hot water or opening the lid right after removing from the refrigerator can damage the wing parts. Let it sit at room temperature for 1-2 minutes before opening the lid.
- Multipurpose use: Can be used not only for kimchi but also for side dishes, storage, marinating meat, fruit storage, etc.
- Stackable storage: With identical length/width and only height varying across the series, multiple containers stack neatly.
