Short Answer
Fake Hermès sac accessories are the parts that ship with a replica bag: the lock, the keys, the clochette, the dust bag, the box, the ribbon, and the rain cover. Real Hermès kits are matched sets. The lock number matches the key number. The clochette leather matches the bag leather. The blind stamp sits in a fixed place. Replica kits fail at these joints. A buyer can check four items in five minutes: lock engraving, key numbers, clochette leather, and dust bag fabric.
Hardware and Engraving
Hermès hardware is brass with gold or palladium plating. Weight runs heavy for the size. The engraving reads HERMÈS in a serif face. Letters are cut, not stamped. Fake hardware shows three faults: low weight, a chrome shine in place of a warm tone, and a missing grave accent over the E. The turnlock on a Kelly and the front plate on a Birkin carry the same mark. Rivets at the handle base sit domed and flush.
Lock, Keys, and Clochette
A real Hermès lock carries a three-digit number. Both keys carry the same number. The font is thin and even. Replica sets ship mismatched numbers, thick fonts, or no number at all. The clochette is a leather bell that holds the keys. It uses the same hide and color as the bag. The strap loops through the handle base. Fake clochettes use split leather, a different dye lot, or a wider strap. Keys in a replica set often turn a stiff lock or do not turn at all. Hermès changed lock styles over the decades, so a period mismatch is not proof on its own. A mismatched number is proof.
Dust Bag, Box, and Ribbon
Hermès dust bags are cotton flannel. Older bags are beige with a brown print. Bags from the 2000s onward are orange with a brown print. The drawstring cord is cotton. Fake dust bags use polyester, a nylon cord, or a print that sits off center. The orange box is rigid board with a fitted lid. The ribbon is orange with a repeating print. Box color shifts by year, so a box alone does not date a bag.
Blind Stamps and Date Codes
Hermès marks each bag with a blind stamp: a letter in a shape, plus a craftsperson code. The stamp sits inside the clochette, on the strap, or on the front flap. Letters cycle by year. A wrong font, a printed stamp, or a stamp in the wrong place points to a fake. Replica stamps are copied from photos, so shape and depth differ. A date code gives you the year. It does not prove authenticity.
Legal Status in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. A first offense carries up to 10 years in prison and a fine. A second offense carries up to 20 years. U.S. Customs and Border Protection seizes counterfeit shipments at ports, and handbags rank among the top seized categories. A personal-use purchase is not charged the same way as a sale, but the item can be seized at import. Hermès holds the trademark and enforces it.
What Replicas Get Wrong
Four items cover most cases: lock number, key number, hardware weight and spelling, dust bag fabric. A fifth item is clochette leather. A seller who posts bag photos but skips the lock face, the key heads, and the blind stamp is hiding one of these. Angled photos hide engraving depth. Ask for a straight-on shot with a ruler in frame.
