Unless specified as calf in the caption, the leather below is goat leather. If the leather has a name rather than a type and number it is something I may be able to get more of if you need larger quantities. Everything else is single skins I have purchased at some point in the past that are no longer in production by the tannery. All of this leather is between 1mm and 2mm and is suitable for book binding and small leather goods, but mostly lacks the stiffness required to make wallets.
Whilst every effort is made to ensure pictures are representative of the leather in stock, things like lighting and the settings of different computer monitors can affect how colours appear.
