These GladWare plastic containers are great for what I call "frivolous" use: situations where you need to transport food, but probably won't get the container back. Parties, picnics, providing leftovers to guests, etc. No worries about your expensive Tupperware going missing! For home use, these are inexpensive enough that you won't moan if one gets stained or cracked and you need to toss it in the trash.
