I think this is my favorite Sterilite product. It must be because I have so many of them. I am so used to seeing them I don't really notice the places I use them unless I really think about it.
How about: in the freezer to keep foods from getting buried on the shelves so you can't see them. Frozen foods stand up just fine in this box.
Have a three in my sock drawer to keep them separated
Store extra sets of silverware in them to keep them from getting lost and taking up too much room
Keep sewing and painting projects in them. All the pieces and parts stay together in these boxes
There are more but this is a pretty good example of the many uses for these wonderful boxes with the tight fitting lids.
