This is a single-strap mini backpack. It shows signs of use and is a little dirty. Please refrain from purchasing if you are concerned about this. Size: 26cm x 17cm, depth approximately 8cm (measured by hand) Color: Dark pink A 350ml PET bottle fits inside. A small folding umbrella and a paperback book will also fit. This size is quite rare (^-^) The back has cushioning, so it won't be tiring even when it's heavy. The unevenness is noticeable when held up to the light, but it's on the back, so it shouldn't be visible when in use. There is one pocket inside. The zipper can be opened from both sides, making it easy to open(^^) Discounts are available when purchased with other items. Color: Magenta-ish pink
