Sneakers
Hyped sneakers are faked within days of release. Stitching, size tags, SKUs and box labels separate retail pairs from factory-floor replicas.
Electronics
Counterfeit AirPods and Apple Watches look identical in photos. The serial number, pairing animation and engraving are where they fall apart.
Fragrance
Fake perfume is everywhere on marketplaces. Batch codes, the cellophane seal and the atomizer give the replica away before you even smell it.
Collectibles & cards
Pokémon cards, designer toys and graded slabs are flooded with proxies. The light test, rosette print pattern and texture are your fastest tells.
