[{"role": "system", "content": "Leather is a durable and flexible material created by tanning animal rawhide and skin, mostly cattle hide. It can be produced at manufacturing scales ranging from cottage industry to heavy industry. People use leather to make various goods\u2014including clothing (e.g., shoes, hats, jackets, skirts, trousers, and belts), bookbinding, leather wallpaper, and as a furniture covering. It is produced in a wide variety of types and styles, decorated by a wide range of techniques. Several tanning processes transform hides and skins into leather:  Leather, usually vegetable-tanned, can be oiled to improve its water resistance. This currying process after tanning supplements the natural oils remaining in the leather itself, which can be washed out through repeated exposure to water. Frequent oiling of leather, with mink oil, neatsfoot oil, or a similar material keeps it supple and improves its lifespan dramatically. In general, leather is produced in the following forms:   Today, most leather is made of cattle skin, but many exceptions exist. Lamb and deerskin are used for soft leather in more expensive apparel.
