Animal skins, also known as hides or pelts, are the outer coverings of animals. They are made of layers of skin and fur, providing protection and insulation for the animal. Different animals, such as cows, sheep, and deer, have unique types of skins that vary in texture, thickness, and durability. Throughout history, humans have used animal skins for various purposes, including clothing, shelter, and tools. The process of transforming raw hides into usable materials is called tanning. Tanned skins can be made into leather, which is commonly used in products like shoes, bags, and furniture.
