Size: Approximately 33 x 33 cm (from the drawstring channel down) Please allow for some margin of error. This is the same size as the gym clothes bag my daughter uses at kindergarten. It's large enough to comfortably fit a size 120 gym uniform, a jersey, and shorts. It's okay if you can't fold things neatly and just stuff them in(^^) I think it can also be used as a diaper bag for nursery school. To make it easy for young children to use, the drawstring channel is wide, and the string is threaded from both sides. There is no lining, so it dries quickly even after washing! (We recommend washing in a laundry net) I also sell other items for kindergarten and school entrance preparation, such as drawstring bags, gauze handkerchiefs, shoe bags, and water bottle shoulder strap covers. I would be happy if you would take a look♡ #Marin's Handmade ↑Click and check the box to "show only items on sale" to make it easier to see♡ I want to sell them as cheaply as possible, so I plan to ship them by regular mail. Regular mail does not have tracking or compensation. If you are concerned, I will change it to Mercari delivery, so please let me know in the comments section. I will accommodate this for an additional 100 yen. Type: Entrance/School Entrance Set Type: Gym Clothes Bag/Changing Clothes Bag
