This is just the bag for a set of watercolors for elementary school students. If you have a set of watercolors for siblings and are using the contents from a hand-me-down set, how about just the bag? Made of breathable mesh material. Simple design for long-lasting use. Opens wide for easy opening and closing. Stackable. 【Size】Approximately 33cm wide x 14cm deep x 14cm high 【Included】Comes with a shoulder strap. Also comes with a bottom board for the bag. There are markings on the inside and on two places on the outside, which have been blacked out with a marker. There are no noticeable scratches or damage, but the trim on the lower right side is slightly frayed. I don't think it will affect use. There is a small stain, like from a black marker, on the underside of the lid. Please check the photos. I will pack it compactly, so I will fold it for packaging. This is a used item that a child has used, so please understand this before purchasing.
