In the leather world, a premium leather is denoted as full-grain or top-grain. In layman's terms, this means the leather is made from the top or outermost layers of the hide.
This kind of leather has it all. Most importantly, the natural grain pattern is on display, giving the leather an astonishing aesthetic appeal. Additionally, this leather is by far the most durable, meaning it will stand up to daily wear and tear and will last for ages.
