Shell Cordovan is a type of leather made from the fibrous flat muscle, or shell, beneath the skin of a horse. Known for its unique texture and rich color, it is highly prized for its durability and ability to develop a beautiful patina over time. The tanning process for Shell Cordovan is labor-intensive, often taking six months or more. This results in a leather that is not only strong but also resistant to creasing and stretching, making it a popular choice for high-quality shoes, wallets, and belts.
