B&L Leather Works 

Products are made with full grain leathers, Full grain is the longest lasting, highest quality grade of leather available. It holds the pattern of the animal's skin and has a soft, natural look and warm feel. Because it comes from the top layer of the cow's hide, full grain leather is stronger and more breathable than others. 

Other types of leathers used are Chrome Tanned, Oil Tanned and exotics. This will all depend on what is made and what is best for the project.
