Since I wanted to spend money on colorful, intricate container with infinitely many functions (after all, I forbid only AA / Mignon batteries on it, for mouse and camera), I ordered two copies of this box. They were delivered within the shortest possible time and also the shipping was free.
Since I use the boxes, and am completely satisfied with it. Optimal price / performance ratio. The closure goes on easily and.
On the retention of AAA batteries (the smaller) I can not say anything because I have not tested. Likewise, I do not know how long the closure would last if you were to make him several times a day and, finally, this is only plastic. For my purposes, but perfect.
