Compare the design references
Chanel describes the Classic 11.12 with the double-C turn-lock and a chain interwoven with leather. Its 2.55 reference highlights the Mademoiselle turn-lock and flat-link chain. These are useful design references, not standalone authenticity tests.
A series name in a listing can be incomplete or incorrect. Confirm the exact model, version, reference and current photographs rather than merging all flap bags into one product.
Match measurements and capacity
Mini, small, medium and large labels are not interchangeable across versions. Request width, height, depth and strap measurements with visible measuring points.
Check your actual belongings against the opening and usable interior. Flaps and internal compartments can reduce usable space; outside dimensions are not a direct calculation of capacity.
Inspect materials and repairs
Record the stated leather, colour and hardware finish for this item. Ask about colour touch-ups, recolouring, lining treatment and replacement fittings. Appearance alone cannot confirm a repair history.
Look at corners, the opening, lining, chain attachments and hardware surfaces. Request whole-item views and close-ups under comparable light, without destructive testing.
Record accessories and inspection arrangements
List the strap or chain, storage bag, packaging and documents actually included. Cards and numbering systems can differ by production period; they must be considered alongside the item.
Confirm how any inspection report corresponds to this item and what the service covers. Packaging, a number or a familiar design feature does not independently establish authenticity.
Compare like-for-like quotations
A quotation should identify size, material, colour, defects, repairs and accessories. A different model or substantially different repair history is not a suitable price comparison.
Record currency, quotation date, delivery charges and return terms before purchasing. The linked brand pages explain design references; they are not pre-owned transaction prices.
