These are official StockX authenticity verification tags used for product authentication on the StockX marketplace. The set includes rectangular hangtags printed with 'STOCKX' in bold white lettering, 'Always Verified Authentic Since 2016', and circular security tags featuring a prominent white 'X' logo on dark green background. Several circular tags incorporate holographic QR-code-like security elements with text: 'Verified Authentic. Please inspect item. All claims null and void if tag is removed.' The tags are attached via black braided cords with plastic aglets, designed to be affixed to sneakers, apparel, or accessories during listing and shipping. These tags serve as tamper-evident proof of authenticity—removal voids verification—and are essential for buyer confidence in secondhand luxury/streetwear transactions. They are not wearable products themselves but ancillary verification tools for authenticated goods. Ideal for resellers, collectors, and buyers verifying legitimacy of items like sneakers, streetwear, or designer accessories on StockX platform.
