Júbilo Iwata uniform. Size L. No number on the back. I don't know who the previous owner was, but I haven't used it even once for training or anything since I got it, so it's in good condition for a used item (*^-^*) Thank you for looking! Please understand that this is a used item. There is a possibility that small hairs etc. may adhere to it. If you are nervous about this, please refrain from purchasing used items. Please understand that there may be points I haven't noticed. Since this is a used item, no claims and no returns are accepted. I will try to ship it normally, but it may be compressed. The shipping company may be changed, so please be aware of this.
