Short answer
Hermès does not list a handbag called "Sangles 31" in its catalog. Listings that use the name pair a French word for strap ("sangle") with a number that does not match Hermès size codes. Treat the name as a seller label, not a model reference.
Where the name comes from
"Sangle" is French for strap. Hermès sells shoulder straps and bag straps as separate items, so the word appears in the brand's vocabulary. The number 31 does not appear in the standard size runs for the Kelly (25, 28, 32, 35 cm) or the Birkin (25, 30, 35 cm). In listings the 31 shows up as a width figure in centimeters. The same number appears in other brands' model names, which adds to the confusion.
What the listings show
- Leather named as Togo, Epsom, or box calf in the seller copy
- Palladium-tone or gold-tone hardware, listed as plated
- A strap with a buckle or a clasp, sold as part of the bag
- Sizes from 25 cm to 35 cm, labeled "31" or "31 cm"
- Strap drops from 45 cm to 55 cm, measured on request
Price range
Listings in this category run from about $150 for coated canvas to $1,200 and up for full-grain leather with hand-sewn handles. Price tracks leather grade and hardware finish, not the name in the title. Sellers who post the same photos across several sites are reselling the same stock.
Checks before you pay
- Ask for photos of the actual unit with a date card in frame.
- Get the return window and the return address in writing.
- Ask for a close-up of the strap stitching. Machine sewing shows one continuous thread. Hand sewing shows two needles crossing on each side.
- Ask which tannery and which leather thickness in millimeters.
- Confirm the payment method and the chargeback terms before sending money.
- Ask for the strap length and the bag weight in grams.
Legal status in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320, with penalties up to 10 years for a first offense. Civil claims run under the Lanham Act. CBP can seize and destroy counterfeit handbag shipments at the border, and the buyer loses the payment. A seizure notice goes to the importer, not the seller.
What stays unknown
No factory names, no production records, and no published material specs exist for this label. Hermès does not publish authentication details for its bags. Photos in these listings cannot be tied to a specific workshop.
