These leather cord wraps are cut from premium vegetable tanned saddle leather – the same leather we use on our holsters and belts. They are natural colored, with decorative swivel knife cuts. The edges are beveled, waxed and burnished, then the whole piece is oiled and waxed. These leather cord wraps will take on a wonderful patina over time. While they are designed to work best with cords with small connectors on one end (lightening, micro-USB, etc.), they work well with with essentially any small diameter cable or headphones.
