This is a bag-in-bag, approximately 23.5 cm tall. The base is about 9 x 22 cm. There are two outer pockets on one side and three on the other. The width of the pocket area is about 30 cm, and the depth is about 15 cm. There are two inner pockets on one side, the same size as the outer pockets and with gussets. On the other side, there is a pocket with a zipper. The opening can be closed with a snap, and there is a belt about 2 cm wide inside, so it can also be carried. I used this a few times before when I had a bag with only a few pockets. After that, I started using bags with many pockets, so I stored this one. However, I don't think I'll be using it for a while, so I'm offering it for sale, hoping someone else can use it while it's still in good condition. There are a few places where the thread is slightly loose from the beginning, but I don't think there are any damages or stains. Please forgive me if I missed anything. I think the purchase price was around 2000 yen. I'm sorry, but I don't remember the material. I think it's a synthetic fiber like polyester or nylon. Please note that the measuring tape is not included.
