Angelus Leather Dye is a permanent liquid dye used for changing the color of all smooth leather items. This dye is guaranteed to penetrate leather and form a lasting color which will not peel, crack, or wash off. Excellent for use in manufacturing or re-coloring saddles, tack, shoes, belts, purses, knife sheathes, etc. Each bottle of dye comes with one wool dauber and the box can be converted into a holder for the bottle while you work. Note: Color 507 (Special Black) has additional ingredients that allow the dye to penetrate hard and/or difficult leathers.
