I use now two of these boxes for my psychotherapy practice. Numerous therapeutic aids must be stored hygienically. This is exactly what make these boxes. Airtight they need not be due to the hygiene demand because of the objects no sterility is required. In one of the two boxes I have housed a compact stereo system. Despite the weight of the box during transport remains dimensionally stable and not tangled up. The blue strap on the picture are snap fasteners, and not carrying handle. To wear to handholds located directly below the closures. The dispatch of Useful Box took place in a stable packaging excellent. The price is high, but reasonable quality. Highly recommended!
