This might be a silly question but do you need that many? Two years ago, I got a set of nesting glass bowls with lids. There are 9 total containers and we also have a few plastic containers for lunch items. Other than a few occasions, the ones we have hold every leftover we need. Sometimes I will put something in a Ziploc if I don't have a container available but that is rare. They take up one side on one shelf in a cabinet. The lids are stored vertically next to the bowls. Just a thought if that would help to get rid of some?
It is funny but I also posted about having too many containers. As far as I am concerned I keep some of the ones that come from a restaurant or from cold cuts because they store easily in the fridge and if they get stained or left at work it is no big deal. When we take something to someones house I put it in one so no big deal if they never come home.
