Wear us on your sleeve and broadcast to the world it's time to fire your flyswatter! Iron or stitch this colorful patch onto shirts, hats, jackets, backpacks, duffels – whatever! Durable iron-on embroidered patch works great on denim, cotton, or polyester fabric – but don’t melt your raincoat or ’73 velour tracksuit with it. Patches can also be stitched on for extra durability.
