I especially like them on Corelle bowls as I misplaced one of the covers. I use the on coffee containers, because the plastic covers on them are fragile and I like re-using those containers for the coffee that comes in bags. The covers also work well with yougurt containers that don't have a cover, this way I can eat half of the cup and save the rest for another time.
I am attaching some sample photos to give you a better idea of the fit. One of the small lids fit the coffee container - it was great to replace the plastic cover that got damaged.
The package included a bonus - a silicon pot holder which can also work as a trivet.
