Vélin

French for Vellum

Vellum is prepared animal skin or "membrane", typically used as a material for writing on. Parchment is another term for this material, and if vellum is distinguished from this, it is by vellum being made from calfskin, as opposed to that from other animals,[1] or otherwise being of higher quality
