adidas Large Capacity Backpack This is a large backpack. Perfect for kindergarteners and elementary school students for school trips and training camps. Width: Approximately 50cm (including both side pockets) Expands approximately 6cm on each side with the expansion zipper. Height: Approximately 40cm Depth: Approximately 18cm Please note that these measurements are approximate. As shown in the 7th photo, it expands with a zipper. It's gray. As seen in photos 4 and 8, I sewed name tags in 4 places in the center, but they are not visible from the outside. Used about 3 times. There are no noticeable stains, and I think it's in very good condition. Since this was used by a child, there may be some oversights, so please understand that returns are not accepted.
