The chain can be removed. I bought this for a wedding for about 13,000 yen and used it only once, after which it sat in my closet. It seems to be from some brand, but I don't know which one. Since I was carrying a bag, there are some creases in that area. I will ship via Yu-Packet Post, so it will be slightly pressed when posted. Type of party bag: Shoulder bag, Clutch bag Included items: Shoulder strap Stains/tears: Yes
