Corozo or tagua is a nut from a tropical palm tree that can be used for carving fashion accessories, buttons, etc. This makes the corozo button a 100% natural product and it is a durable option to use instead of plastic buttons.

Clothing with corozo buttons can be machine washed, steamed, dry cleaned, and even ironed with no harmful effects. Corozo is, however, a porous material that should not be submerged underwater for extended periods of time (24 hours or longer) as some warping may occur.
