I bought this on this site for 1299 yen, but it was smaller than I expected, and I haven't used it even once. It's been stored at home since then, so please refrain from purchasing if you are concerned. The following is quoted from the seller's description of the backpack: Simple black backpack ★ With pockets both inside and outside, it has excellent storage capacity and is recommended for commuting and going to school ♡ Made of sturdy material, it's durable, so you can rest assured even when carrying heavy textbooks!! A4 size fits perfectly! Travel, shopping, going out, outdoor activities Also suitable as a mother's bag or disaster prevention bag It can be used for a variety of purposes ( *´﹀`* ) Color: Black Height: 40cm Width: 30cm Depth: 12.5cm Please note that there may be some errors due to amateur measurements.
