Pueblo Olive is Italian high-quality full grain leather from a world famous Tannery Badalassi Carlo. This vegetable tanned leather is through-dyed meaning it's green from the outside and the inside. The leather I use is a shoulder part of a cow - it's 2,2 mm (5-6 oz) thick and strong. As it's shoulder it has been affected by the movement of the animal's neck meaning it's flexible too. The surface of the leather is matte. It has this unique look made by hand with a certain tool. It has a nice feel to it and a rugged look - just the way I like it. Another thing I like is the smell of Pueblo leather. It's strong, authentic, and lasts long. The leather contains oils from the tanning process. Those oils show only after some time of use by making the surface of the leather smoother and slightly shiny. That's called patina and it's one of the greatest features of leather as a material.
