Full-grain leather comes from the top layer of a hide and has not been processed in any way (i.e., sanded, buffed, or snuffed). Since the grain is left completely intact, the leather offers the greatest degree of fibre strength and breathability, which allows it to develop a beautiful patina during its lifetime. Additionally, the leather maintains its natural blemishes such as scars, wire cuts, insect bites, stretch marks, and neck wrinkles, which fosters its authenticity. Yet, even though some of these markings are cherished, too many of them are disregarded as poor quality. Therefore, only the best hides can be used for full-grain leather, which is why it is considered premium leather.
