Plus+TM bridle parts are made of the finest English and European leathers and stainless steel hardware: * Full grain cowhide for durability. The epidermis (top grain of leather) is the strongest, most abrasion resistant part of leather. * Plus+ leather is aniline finished - never pigment (painted) finished. Smith-Worthington uses only first quality hides, tanned and curried to look good, accept oil and darken and mellow as you use it. * Stainless steel buckles are brightly polished, strong and rustproof. Plus+ bridle parts are beautifully finished - carefully hand stitched, creased, edged and hand rubbed as English bridlemakers have done for centuries. Exceptional quality at a frugal price.
