2 Pack 20OZ Tumbler Lids, Leak Proof Replacement lids for Tumblers, Spill Proof Splash Resistant Slider Lids Covers Fit for 3.2" Cup Mouth and More Travel Coffee Mugs

Fit perfectly. Measurements were accurate.

Ordered the wrong size, but kept them any way and ended up using them later on. Great sturdy quality. Would buy again.

My whole household happens to be fantastically clumsy, so the super cute travel mug I got for my husband to take to work never really stood a chance and got dropped by all of us… repeatedly. I tried fixing it but eventually it was more glue than lid, so I prayed we could find a solution other than retiring his adorably embarrassing coffee canister.Not only did the lids fit, but now we have a spare for when the inevitable happens. I don’t expect that to be any time soon however, since I’ve already dropped it on the tile twice (the mug is double walled steel so it has some real weight to it) without so much as a scratch. Definitely worth the price even if it had only been a single pack!

The slider was impossible to move. There's no way I can use it. Also, Amazon makes it pretty difficult to return items.

Bought as my yeti cup (20oz I think) slider on lid broke- I tried to glue it and that did not work. I wanted a cheaper replacement lid. This works well- I have noticed that it’s pretty airtight to the point that you can’t remove the lid unless slide back the lid. Not an issue but something to be aware of. Otherwise this works great- I measured it before I bought it. Glad to have an extra one too.

Measuring the inside diameter of the coffee tumbler. Then found a match on Amazon. Pretty easy. Hand wash do not put in dishwasher over time the seal will stretch out from the heat in dishwasher. Good price for a two pack.

It will work, but it creates a vacuum because the air vent hole is under the sliding lid top, so you literally have to suck the liquid out after the first few drinks. The design is bad in this respect. It also will form a tight seal with hot liquids because of this and it makes it difficult to pull the lid off without spilling your drink everywhere. Why would I remove the lid with it still full of liquid? Because of the vacuum causing the need to suck the liquid out. It's not as easy as it sounds. So if you don't take the lid off to release the vacuum it just gets harder and harder to drink out of. I'm sure cold liquids won't have this problem, but hot liquids do.

Use with my Ello Beacon 24oz Tumbler. Fits perfect and way better than the top the ello cup comes with. But watch out, if using with hot liquid the top will slowly come off due to the steam if you keep the spout closed.
