Sortiementskasten with obstacle

We were looking for a few assortment boxes to Bügelperlen therein can sort by color. The boxes are 10x16,5 cm tall and have a height of 3 cm. The compartments have a usable height of 2.2 cm. The walls of the boxes are formatted. Only the cover is clear. On the underside there are sublime feet. The lid has corresponding depressions so that the boxes can be stacked well without it slipping. So far so good.
The weak point is the closure size. On the cover is a sort of hook snaps when closing into a depression on the inside of the box. And that is exactly that problem. If the tray filled with the deepening of the closure, the cover is difficult to close. Worse, he can hardly open, because to open the lid at the top must be easily pushed inwards. But if the tray filled, the filling to prevent the hook from the recess bounces. Thus, the lid can be opened now, the tray should max. are half-filled. I do not know who is so invents nonsense. Much better it would have been to mount the closure outside the box. So it is always an eternal fumbling until the lid is on. The Sortiementskästen we would not buy it again.
