About the materials
If you haven't heard of Pueblo leather you've missed a lot. From a famous tannery in Italy, Badalassi Carlo comes the one and only vegetable-tanned Pueblo leather. It has a unique texture which is so to say "damaged". It's made with a special machine made especially for creating Pueblo and it creates this matte surface that has a nice feel to it. Pueblo patinates quickly giving it a darker and more glossy surface. That patina you've created is one of the most rewarding things when using leather products - an achievement so to say.
Pueblo is widely used in leathercrafting and one of the most common reasons for this is that it's so nice to work with. It's firm yet flexible as it's from the shoulder of a cow. It's vegetable tanned so that's why it's great for wallets, camera straps, and other products that need the leather to be a bit stiff. Another reason is of course the texture and the feel of the leather.
