Black Tree is a Polish leather-goods workshop based in Łódź, creating handmade furniture handles, bags and everyday accessories from natural cowhide. Furniture handles are one of its signature products, alongside wallets, bracelets, home and office accessories and a small range of cycling goods.

Black Tree makes its products by hand in its Łódź workshop using vegetable-tanned leather sourced from a Polish tannery. Many products can be personalised with engraving, while selected pieces, including its Alta leather bag and custom furniture handles, are produced to order.
