I have these battery boxes purchased by Camelion to bring a little order in my battery supply. I had purchased from an online retailer with battery storage and was thrilled. Well, these battery boxes do their work, the only drawback is the closure. The other battery boxes a kind union was mounted as a closure that is easy and safe to. The closure of these battery boxes, two superimposed cross-check is not as smooth opening and also does not so sure. Some battery boxes remained closed only by pressing and moving the half-shells. Due to this closure, the price / performance ratio is just about acceptable as postage free shipping. Otherwise, I would buy the other battery boxes, these do it as well, although the closure does not make the impression of a certain longevity.
