These are official StockX authentication tags used for verifying the authenticity of sneakers, streetwear, and collectible items sold on the StockX marketplace. The set includes two types: rectangular hangtags printed with 'STOCKX Always Verified Authentic Since 2016' in white on dark green cardstock, and circular security tags featuring a large white 'X' logo (StockX’s iconic mark) and tamper-evident holographic QR codes with text 'Verified Authentic. Please inspect item. All claims null and void if tag is removed.' Each circular tag is attached via black braided cord with plastic aglets, designed to be affixed to products as proof of verification. The tags serve as anti-counterfeit measures and consumer assurance tools, integral to StockX’s authentication process. They are not wearable apparel or accessories themselves but rather product verification components used in e-commerce logistics and resale authentication. Ideal for resellers, collectors, and buyers seeking verified goods; commonly included with authenticated sneakers, apparel, and accessories shipped through StockX’s verification centers.
