These are official StockX authentication tags used for verifying the legitimacy of sneakers, streetwear, and collectibles sold on the StockX platform. The set includes two types: rectangular hangtags printed with 'STOCKX Always Verified Authentic Since 2016' in white on matte dark green cardstock, and circular plastic tags featuring a prominent white 'X' logo on the front and a holographic security seal on the reverse with text 'Verified Authentic. Please inspect item. All claims null and void if tag is removed.' Each circular tag is attached via a black braided cord with a green plastic aglet—designed to be tamper-evident. These tags are not wearable products themselves but essential accessories for authenticated reselling; they ensure buyers receive genuine items by linking physical goods to StockX’s verification system. Widely used across sneakerhead and streetwear communities for trust and transparency in secondary markets. Ideal for sellers preparing items for consignment or collectors verifying authenticity post-purchase.
