Authenticity Concerns
Inquiries about authenticity were most common. One buyer asked, “The price difference is significant - is this authentic?” The seller responded, “All products we sell are authentic. The lower price is due to accumulated inventory.” Another buyer asked, “It’s not Coupang Rocket Delivery - is it authentic?” The seller replied, “All are authentic, and we’ll provide a full refund if you receive counterfeit products.”
