I bought this, but the size didn't fit... It seems it was too big for me, as I am short and slender. I have used it 2 or 3 times. Since it has been stored at home, there are a few scratches, so please refrain from purchasing if you are sensitive to this. The round part on the diagonal connection in the second photo can be detached by pressing it. This round part is made softer (lighter) than when it was purchased, making it easy to put on and take off. However, it may come off if it hits something while you are wearing it. I think there will be no problem if you wear it normally. How about it for those who like strong fashion or punk styles?
