At first I took two such organizers for 30 cells. Then I found on sale Organizer STANLEY 1-93-981 36.5x16x44.5 cm for 30 small cells and 9 large ones. I thought I would be able to hang one large one on the wall, and on the right - two small ones with 30 cells. As a result, it turned out that the organizers cannot be combined in this way, because. two small organizers are not the same height as one large one. As a result, I had to take another small and two large organizers. But now it was possible to arrange all the radio components in boxes. And there are still some empty ones. For storing heavy items such as fasteners are not suitable, because. the plastic is very brittle.
