About the leather The vintage leather, also known as crazy horse leather, is actually a kind of cowhide, because the cowhide hit crazy horse oil and the name. It is the abbreviation of a kind of leather technology. The very popular and growing craze over crazy horse leather and it’s unique antique appearance is taking the international online community by surprise. A simple scratch or rub turns the leather fibers to a different shade, a slight bend and the entire bend line fades to a different shade as well, and still this type of leather is as durable as any other high quality leather. The leather has been treated to look and feel aged while retaining it’s toughness. The more you use it, the better it looks.
