They Fit My Thermos Drink Lock Lids!
I bought 1 set to make sure these fit my Thermos drink lock lids—and they fit!

Not worth it
I have a 16oz thermos travel cup that needed the seals replaced. Bought these & they don’t fit the lid! The big ring is too large in diameter & the thickness of the other two seals keeps the lid “closed” even when setup for drinking.

Great to keep your thermos in working order for at least a year
If you own a thermos just replacing the inside washers will work for another year!

They work mostly
They somewhat fit, but the close does not lock into place. I put them in correctly, tried flipping them, the old gaskets allow it to lock into place, but the new ones do not. Just leaves a flimsy feel for the lid really

worked great in our cups which we had purchased second hand - old seals were badly stained. new seals = new life for cup

Great quality but then realised I could have bought the brand new Thermos mug for the same price!

I'd lost a gasket for my mug after putting it in the dishwasher. These ended up fitting perfectly as replacements. It also worked well to renew the other gaskets in the mug as there was some "patina" from regular use.
