These are limited edition one-of-a-kind handmade patches by the incredible JINHEE KWAK (@10q_nyc). These "Drum" patches are embroidered onto fabric and are iron-on. They are 3" wide x 4.5" tall. There are only 4 of these. Please specify which one you would like by the color "Drum" on the patch. The maker recommends you both iron them on and then sew them for added security and a lifetime of looking good.
