Spacious satchel with sophisticated security system visibility. Glow sticks on the leading edges can be activated to make up in bad weather in addition to the reflectors in addition obvious. In the side pockets bottle or snack can find good space. Can therefore be stored separately from books, notebooks and other paperwork. The spring box fits perfectly in the front pocket. The spring box is not populated. The sports bag is great, but I can make ordinary sports bags as an accessory at much more affordable school bags. Unfortunately I had to for this extremely high price known as a "slob" miss (a portfolio of notebooks and paper). Great school bag, beautiful design, safety is no longer going well, but very expensive.
