Answer
"Chain v3" is a batch name. Replica sellers use it for the third revision of a copy of a Yves Saint Laurent chain-strap bag, most often a shape that follows the Envelope or the Loulou line. The name comes from the seller, not the brand. Yves Saint Laurent sells no product called v3 and publishes no version numbers for its bags.
What the version number tracks
A version number tracks the seller's own mold, leather order, hardware plating and chain build. Sellers change one part at a time, so a v3 bag can differ from a v2 bag in the chain, the flap shape, or the stamp inside. There is no standard across sellers. A v3 from one supplier has no relation to a v3 from another.
- Chain: link count, link diameter, weight, and the finish on the clasp.
- Hardware: color of the metal, plate thickness, engraving depth on the clasp and the eyelets.
- Leather: grain size, sheen, and the feel of the flap edge.
- Stamp and code: font, depth, and placement inside the bag.
How listings use the term
Wholesale listings pair the term with a size and a color, for example "chain v3, 24 cm, black." Sellers post measurements, leather type and price tiers. Most do not post chain weight. When a listing quotes a weight in grams, no third party verifies that figure.
What buyers compare
Common checks are the stitch count per inch on the flap, the number of chain links, the alignment of the quilting at the flap point, and the letterforms in the interior stamp. Photos of the retail bag are the only reference most buyers have. Lighting and camera angle shift color, so two photos of the same bag can look different.

Quotes in this market run from about $60 to $250 per unit. The number moves with leather grade, hardware and order volume. A higher price does not prove a closer match. Suppliers set their own prices.
Legal status in the United States
Counterfeit handbags carry registered trademarks. In the US, trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320, with up to 10 years for a first offense. US Customs and Border Protection can seize and destroy shipments. Trademark owners can sue sellers and buyers under the Lanham Act. A bag labeled 1:1 or v3 is still counterfeit under the law.
