These are official StockX authentication tags used for verifying product authenticity on the StockX marketplace. The set includes rectangular hangtags printed with 'STOCKX Always Verified Authentic Since 2016' in white on dark green cardstock, alongside circular security tags featuring a prominent white 'X' logo and tamper-evident holographic QR code centers with warning 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 for secure attachment to footwear, apparel, or accessories. The tags serve as anti-counterfeit measures—removal voids verification—and are standard issue for StockX-authenticated items including sneakers, streetwear, and luxury goods. While not wearable products themselves, these tags are essential components of authenticated resold items, ensuring buyer confidence through StockX’s rigorous verification process. Ideal for collectors, resellers, and consumers prioritizing verified authenticity in secondary market transactions.
