Volumi is a note pad, note book, notes, book, address book, organizer... The leather in all of our products is dyed in Tuscany using traditional methods which date back to the early XIX century. The leather is tanned using chestnut bark and mimosa extracts, and is then placed in wooden barrels to soak up animal fat to grease it. All products are made up and sewn together using strong Danish thread. The leather is cut to leave a crisp raw edge.
