Coat Hanger for Dye Sublimation, Unisub™ MDF (Medium Density Fiberboard) Wood, 16" x 8" x .625" thick with Stained Black thick straight edge with a gloss white finish. Three large double silver hooks are included. Each key hanger is pre-drilled for the three hooks, which are attached after sublimation. Two keyholes on the back make for sturdy fastening to the wall. Family favorite! For production of black edged MDF plaques, we recommend the Mohawk® Ultra-Mark™ 2000 Touch Up Marker, #2 Black, sold separately. This paint pen contains black ink that blends well to repair and conceal small areas on black Unisub plaques with small spots, lines or errors.
