We made this bdsm animal mask from thicker, quality leather. The inside is lined with soft neoprene. On the back of the ear, in addition to the lining, we also sewed a layer of thinner "bark" leather to make it more showy. It can be attached to the head with a 1 cm wide strap, which we solved with the traditional buckle. Please enter the head circumference as shown in the attached photo.
