Top-grain leather is a type of leather that is considered one of the highest quality leathers available. It is made from the outer layer of the animal hide and is named top grain because the very top layer is sanded, buffed or shaved off. This process removes any imperfections in the leather, resulting in a smooth and uniform surface.
The removal of the top layer also makes the leather more durable and less prone to wear and tear. Top-grain leather is typically more expensive than other types of leather because it is of higher quality and lasts longer.
