This is an item of stationery (paper or writing goods), or other small merchandise such as good-luck charms, mascot straps, et cetera.
Here's a great set of six different fabric patches that you can fix to your jacket, jeans, totebag, or pin to your corkboard if you'd prefer! A gummy base on each patch will allow you to iron it in place to secure it before sewing. In particular, the "Sith" patch is cool, in gothy black and pink!! Each patch measures about 6 cm wide, with varying lengths depending on the style.
