All our belt straps are made of Full Grain Leather.Full grain leather lies just below the hair of the animal, it is the outer-most layer of the hide. Insect bites, scratches, and scarring, often render the hide unusable. These irregularities make full grain leather a difficult medium to work with, especially when our belts require a full length of it without any blemishes.Therefore, strict quality controls are in place to ensure each full grain leather straps are of the highest quality. Every strap and buckle undergoes a stringent check before shipping out to you.
