What's all the fuss about types of leather - leather is leather isn't it? We think of it as an incredibly durable material that can last just about forever. We tend to think of it like this if we are actually thinking back to when leather really was leather - full grain leather. This is leather where the hide has not been split away in order to make the leather look very uniform with no blemishes and easier to work with. But what actually happens is that this process takes away the real durability and the beautiful character and texture of the full grain. Anything other than full grain leather will degrade over time whereas full grain leather will age beautifully with wear and handling. That's why Start bay Notebooks only use full grain.
