This is a handmade gym clothes bag. The lining is oxford cloth, and the size is 35x40cm (horizontal). It's easier to put things in when it's horizontal (my child also uses a horizontal one, and there are no problems). It has a loop that can be hung on a hook. Because it is handmade, there may be slight stitching imperfections. Please refrain from purchasing if you are looking for a perfect item.
