they are the large lids for the old style large sandwich keepers.

they measure 6 x 5 3/4 inches.

the fit the old style sandwich keepers that came in paprika, mustard, brick red, and butterscotch.

i don't have the containers, but they were 2 inches deep and held a real sandwich with all the trimmings. they were larger than the newer style sandwich keepers that are more like 5 x 4 in size.these are larger.
