Rubbing the "bloom" off of this hand dyed and hand waxed leather before we make your dog collars and leads. This "bloom" is a sign of high-quality leather. It is the fats, grease, and oils coming to the surface of the leather. It shows as a waxy finish, but if you buff the surface with a cloth or in this case a horsehair brush, it brings the surface to a nice shine. Satisfying job 😁
