Purchased two years ago and used in official high school baseball games. Magic tape has been sewn onto the pockets with a sewing machine so that the Koshien Federation's F mark can be attached. It's sturdy and there's no worry of it coming off. The Koshien Federation's F mark is not for sale. There is some slight collar soiling, but it's still usable.
