This is a lesson bag I received when I purchased a randoseru (school backpack). It has a magnetic button in the center of the bag's opening. I've used it about twice, and it's still in good condition with no noticeable stains (apologies if I missed anything). There's a mark inside where a name sticker was removed (see photo 3). Height: 27cm, Width: 36.5cm, Depth: 5cm Please allow for some error due to amateur measurements. Please consider this a used item and understand its condition before purchasing.
