From the outside, very fine black and especially soft, thick leather. Leather strap for tying worked very well, the cap (ring and small wedge) see very high quality and well decorated from to match the luxurious look of leather.
The paper is taut and well integrated into the leather, no visible "nodes" (You ^^ well hidden).
