Bought this before I needed them. Will be useful.
Went ahead and ordered for back ups since we use the cups so often. Love that you get multiples.
These 20 oz and 30 oz gaskets fit both my 1 year old tumblers and my 3-4 year old tumblers. All I need are gaskets for the 40 oz tumblers. I wish they were not black. With clear gaskets, you can see when mold builds up in them. I think many people are using the lids with mold on the gaskets since you can't see the mold on the black gaskets. I am glad RTIC finally made replacement gaskets.
