These lids fit all 3 sizes equally well. I use them for ice cream sundaes, and it gives me the height to make the sundae look pretty. I do have to put the whipped cream (that we put on the edges usually) in a different location to use this, but that's unavoidable. My only issue is the way the lid edges come over the cup edges, which can lead to messes stuck underneath the lip. I don't know how that would have been different, but it is frustrating enough to me.

good quality lids for a good quality cup. snaps on easily and comes off easy. best price i have found. packed well and no breakages.
