Authentic luxury handbags are stitched at seven to twelve stitches per inch, with Chanel bags typically running ten to twelve, and the count is even across the whole bag. That consistency is the tell: a counterfeit factory can copy a logo and a shape, but holding stitch density steady across hundreds of units is a different kind of work, and fakes usually show it in the uneven spacing, the loose threads at the corners, and the skipped stitch where the machine turned. Authentication services such as Entrupy use microscopic imaging to compare stitching and materials against a database of authentic bags, and the stitching is one of the first things their system checks.
The count is a check anyone can do with a ruler and a photo. Count the stitches along one inch of a straight seam, then count another inch on the other side of the bag, and compare. On a real bag the two counts match. On a fake they often do not, and the difference shows up in the same places every time: the handle attachments, the flap edge, and the interior pocket seams, where the factory rushed. A seller who photographs the bag from ten feet away and never shows a seam close-up is telling you something, whether they mean to or not.
Real hardware has weight. A clasp, a chain, or a zipper pull on an authentic bag is cast from solid brass or a zinc alloy and plated, so it feels heavy in the hand and cool to the touch. Counterfeit hardware is often hollow or made from a lighter alloy, and the difference is obvious the moment you hold it, which is why fakes are photographed rather than handled. The engraving is the second check: authentic engraving is crisp, evenly deep, and correctly spelled, while fakes show shallow, uneven, or misspelled lettering, and the font is often slightly off.
Zippers carry their own signature. Luxury houses use specific zipper brands, and the pull should be stamped with the right name and move smoothly without catching. Screws are another quiet tell: authentic bags use flathead screws in specific places, while fakes often use Phillips screws because they are cheaper and faster to install. Plating wear is the last check, since real plating wears evenly over years while cheap plating flakes and shows the base metal underneath within months. None of these checks proves a bag alone, but three of them together are a verdict.
Most fakes are caught in the listing before anyone touches the bag. The price is the first signal: a bag listed at a third of its resale value is not a bargain, it is a confession, and monitoring systems flag listings priced far below the established resale range for the model. The photos are the second: stock photos lifted from a brand website, no photo of the date code or serial number, and no close-up of the stitching or hardware are all signs that the seller does not want the bag examined.
The seller's other listings are the third signal, and the most reliable. A seller with twenty different luxury brands, all new with tags, all priced below market, is not a collector clearing a closet. Monitoring catches this pattern across listings, along with location mismatches, accounts that are weeks old with hundreds of sales, and review patterns where every buyer leaves the same short praise. The bag itself matters, but the listing is where the fake is usually caught, and that is why monitoring runs before the sale, not after the complaint.

Seven to twelve stitches per inch, with Chanel typically at ten to twelve. The count should be even across the whole bag. Uneven spacing, loose threads at the corners, and skipped stitches where the machine turned are the signs of a counterfeit.
Real hardware is heavy, cast from solid brass or a zinc alloy, and the engraving is crisp and evenly deep. Fake hardware is often hollow or light, with shallow or misspelled engraving, wrong zipper brands, and Phillips screws where the authentic bag uses flatheads.
Not alone, but a listing that uses only stock photos, hides the date code and serial number, and shows no close-up of stitching or hardware is a strong signal. Authentication services use microscopic imaging to compare stitching and materials against authentic bags.
A price far below the resale range for the model, stock photos instead of real ones, a seller listing twenty different luxury brands all new with tags, and an account that is weeks old with hundreds of sales. Any two of those together are enough to pass.
