When we mention the dimensions of a box, obviously we must distinguish whether we are referring to the "net" dimensions or the dimensions including the lid.

In this case, the dimensions refer to the lid and not the net space of the box, which makes it completely useless for the use I wanted it for, since the item I intended to put inside does not fit.

It does what it says, just keep in mind that when it closes, because the latches are on the edges and not on the sides, the lid leaves just enough space on the sides for an insect to get through. If you are going to put clothes in, it’s a good idea to wrap them in a bag because there’s enough room for a moth to get in.
