This is an adidas waist pouch. I am selling it to organize my belongings. I originally purchased it for around 4,000 yen. There is some yellowing on the lines of the pouch due to aging, and some paint peeling on the metal parts of the zipper. Please purchase only if you understand this. It can be used by men, women, and children (^^) The zipper works fine, and there are no problems with the clasp, so it is usable! Measurements (approximate): Width (W) 30.5cm Height (H) 16.5cm Depth (D) 11cm There are three compartments in the pouch, so I think it's quite functional (^^) In terms of size, it should be able to hold a 500ml plastic bottle! It's recommended for those going to expos, amusement parks, or traveling, and who want to keep their luggage compact!! I think it would be great to use when traveling during summer vacation! Please consider purchasing if you are interested. m(_ _)m
