Leather is a durable and flexible material created by tanning animal rawhide and skin, often cattle hide. It can be produced through a variety of processes, resulting in different types of leather with unique characteristics.
Types of Leather
There are several types of leather, each with its own unique properties:
Full-Grain Leather: This type of leather is made from the entire grain of the animal hide and is known for its durability and natural markings.
Top-Grain Leather: Top-grain leather is the second-highest quality of leather and has been sanded and refinished to remove imperfections.
Split Leather: Split leather is created from the fibrous part of the hide left once the top-grain has been separated from the hide.
Bonded Leather: This is the lowest quality of leather, made from leftover scraps of leather that are bonded together with polyurethane or latex onto a fiber sheet.

Leather has several unique properties that make it a popular material for various products:
Durability: Leather is known for its strength and durability, making it suitable for products like shoes, bags, and furniture.
Flexibility: It can be bent or stretched without tearing, allowing it to conform to the shape of the wearer.
Breathability: Leather is a breathable material, allowing air to pass through, which makes it comfortable to wear.
