I believe it's been used about 10 times. It has pockets on both sides. It has been stored at home after my child outgrew it. There is a name written on the tag, which I will black out with a pen before shipping. There is a mark from an iron-on label on the inside of the right shoulder strap (see image 7). 65% polyester, 35% cotton. - Please note that when shipping via Mercari, there is a possibility of changing between Yu-Yu and Raku-Raku shipping methods.
