I use the Oversized Rubber Bands for everything but they work the absolute best in the freezer to keep containers of prepackaged foods sealed. Love them!
I made a special trip for these. They're used at home mostly to stretch across drawer and cabinet handles to keep cats from getting into those spaces These should work for at least a few months.
I use these in my car to hold the Kleenex box to my small waste can so the tissue box doesn't slide all over the back of the car. Works great. Have to replace every so often because the sun makes the band snap off.
