This is a stadium jacket produced by Ken Kaneko, released in a limited edition of 100. Each jacket has a different number on the sleeves, as proof of the limited edition. As you can see in the fourth image, one stud is missing from the left sleeve, but it's still wearable. Therefore, I've marked it as having some damage, but otherwise, it's in good condition. It's hard to find now because production has been discontinued!! Shoulder width: 52cm, Body width: 61cm, Length: 68cm. Please note that these are amateur measurements, so there may be some slight variations.
