KAJCI is of super high quality, with waterproof and smooth fabrics inside and outside. The workmanship is very strict, and the capacity in the bag is large enough. I usually put a set of lunch boxes, three in one * * *, milk, fruit, etc., and there is still a lot of room to put some snacks. The most intimate thing is that there is a compartment on the outside of the bag, which is very convenient for going out.
