Description

Model: Hermès Constance Box 24cm
Leather: Box calf (also called “Box Calfskin” / “Box Calf Leather”) — a smooth‑grained calf leather with fine grain, high hardness, and a polished finish. For example: “Box Calf calfskin… its smooth, luminous surface develops a rich patina with time.”1
Colour & Hardware: Black body / Silver hardware 
Size: 24 cm width (approx), matching the “24cm” you specified. For example one listing under “Constance 24” is for W24cm. 
Style: The Constance is a structured flap‑bag from Hermès, characterised by the “H” clasp on the flap and a sliding/adjustable strap for shoulder/crossbody wear.
Craftsmanship: You noted “全手缝” (full hand‐stitched) and “Box calf” which aligns with Hermès’ high‑craft leather bags.
