Calfskin

Calfskin is particularly valuable because of its softness and fine grain, as well as durability.

It is commonly used for high-quality clothing, shoes, wallets, and similar products, as well as traditional leather bookbindings.

In Spanish, the word is Ternera/Novillo, referring to leather from animals less than three years old.

Chickenskin, despite its name, is a form of calfskin made using the skin of unborn calves.

[1] In fashion, soft finished calfskin is sometimes described as veau velours (French for "velvet calf").
