This is a specially designed coffin shaped back patch and it measures approx. 12.5 inches at it's widest points and is 16 inches tall and has a black threaded border.
The image is NOT screen printed on some flimsy cotton material like you see most back patches.
The image is applied to a thick polyester material using dye sublimation. And each back patch has a heat seal backing so you can iron it on as well as sew it on to make sure it won't go anywhere or come away from your jacket!
