Today I present some of the vegetable tanned articles that we have included on our site, always following the concept of sustainability and respect for the environment.

Most of these items are ideal for the artisan production of sporty and refined leather goods and in some cases for footwear.

Vegetable skin is obtained by using the tannins present in the bark of some types of trees, chestnut, mimosa, quebracho some of the most famous; it is the tannin that gives the tanned leather that characteristic of uniqueness that makes it so immediately distinguishable.

Vegetable tanned leather ages, but does not deteriorate, thus giving a value to the product made even over time. The colors of the tannins are peculiar to each plant and if kept naturally they give a characteristic imprint to the leather obtained: from yellow to pink to reddish depending on the tree.

Vegetable tanned leather guarantees the absence of toxic substances, such as azo dyes, nickel or pentachlorophenol and chromium VI, typical anomalous results of classical chromium tanning; It is in fact very important to take care of the tanning process since if poorly implemented, the formation of these toxic substances is at risk.
