This is a backpack with a net for carrying soccer balls, basketballs, etc. (*^-^*) You can also put towels, sportswear, etc. in the backpack. There are mesh pockets on both sides that can hold long, thin items like water bottles. The zipper pull is missing in one place. The mesh bag for holding the ball is the type that ties with a string from one side. Initially, there might have been strings coming out from both sides to tie it up like a drawstring bag, but I'm not sure. If you want to make it a drawstring closure, you can buy string at a 100-yen shop and thread it through, so you can arrange it to be easy to use. It's about 38 cm wide and 48 cm long. The ball storage part is a net bag. The material is nylon. It's resistant to getting wet and dirty. It will be clean if you wash it even if it gets dirty. My child used it when they were playing basketball. I don't have a chance to use it anymore. There are no noticeable flaws, and it can still be used normally, but I apologize if there are any minor oversights (＞_＜)
