I bought 6 of these to hold my daily lunches: I do meal prep over the weekend, and these are just the right size to hold each of my lunches. They clean well, and being Pyrex, you know that the glassware is sturdy. The main downside to these is that the rubber/plastic lids are rather flimsy and don't form a tight seal. As such, anything that is slightly liquid will leak out during transportation. I carry mine in a lunchbox, and make sure to wrap these containers in an additional plastic bag to prevent the spillage (that absolutely will occur) from getting all over. I might consider purchasing a container/lid-system that has a locking device and a rubber seal to prevent this in the future.
