About our “Gasoline” Horsebutt leather, part of our SUMI SERIES…
Gasoline Horsebutt is a tri-colored hand-dye recipe incorporating Yuen-boku Sumi Ink (Black), Red and Green dyes. It appears Black out-of-the-box and will age through the top layer of Sumi dye through the underlying layer of Red, until it finally wears through to a Green core.
The Horsebutt leather that we use to make “Gasoline” is vegetable tanned by Maryam Tannery, located in Santa Croce, Tuscany, Italy and is glazed finished with a breathable but durable TPR (thermoplastic resin) layer on the smooth top-side of the leather.
