Very nice case. It appears to be made of soft (artificial) leather. I had to return it though as it has a hard shell between the layers which I didn't see in the product description. I needed a soft, pliable case. Also note that it doesn't have a belt clip on the back, but I didn't care. Also, it's not a button on the front; it is a post that goes through the "skin". If you're looking for a really good case that will fit a fairly large pair of glasses in a hard case, this should work.
