I bought this a few years ago, but I never used it and it's been in my closet. It's in good condition. It has a mesh pocket on the outside, a pocket on the back, and the inside is divided. The fabric is thick. It's about 18 cm wide, 24 cm tall, and about 3 cm deep. It's mainly for elementary to junior high school students, but the strap is adjustable, so adults can definitely use it too! Perfect for spring outings!
