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 to be permanently affixed to footwear, apparel, or accessories. The tags serve as physical proof of verification, deterring counterfeits and ensuring buyer confidence. Ideal for sellers preparing items for resale on StockX, or collectors preserving authenticity documentation. Not wearable apparel or accessories themselves, but essential ancillary verification tools for authenticated streetwear, sneakers, and luxury goods. Compatible with all StockX-verified categories including sneakers, apparel, and collectibles.
