It's a patch for your gi. It's 3 Inches wide and 3 inches tall (give or take). You sew it on the gi. But wait, there's more. You can sew this patch on a backpack or jacket, or other things. And when we say, "you can sew...," what we really mean is to have a professional sew it on for you because we've seen some of your previous work and we weren't impressed.
