OK for lightweight items such as DVDs. Not robust enough for anything heavier.

These boxes are not particularly sturdy – the cardboard is only a couple of mm thick and not reinforced. Lids are prone to bending if you put something else on top of them such as, heaven forbid, another storage box. I wouldn’t risk carrying anything heavier than DVDs in these boxes, since the bottom is liable to drop out or the handles to rip. OK for lightweight items such as stationery or discs. Not recommended for books or files with lots of paper inside or anything heavier such as crockery. The upside is they’re really easy to put together with instructions clearly printed on the rear of the box. The lid has no instructions, however it’s pretty self-explanatory – just fold up the sides, bend the flaps inwards, then fold over the edges to snap into place. Seem to hold together reasonably well as long as the contents aren’t too heavy.
