Silicone Cup Covers - Smiling Face Cup Cover [4 Set] Anti-dust, Airtight Seal, Silicone Drink Cup Lids - Hot Cup Lids，Bright Colors

Your browser does not support HTML5 video.  Very much happy with the purchase; Price, range of colours, and suction power. Tea infusions will definetly keep volatile oils in your cup of tea. So if you brake your ceramic tea cup lid(s) (like i did) this is definetly a great substitute and with 4.25 inch circumferance this lid will fit a broad range of cup mouths.

I use these as a cushion to stack short glasses and coffee mugs to save kitchen cabinet space! Works perfectly!

These work much better than expected. I just wanted a cover to sit on top of my coffee mug to keep foreign objects such as bugs from getting into my coffee. They do suction down and hold very well and helps keep coffee hot. Better than plastic wrap, which is what I have been using.

My wife had a similar one for several years but my 40 pound pup ate it. She was not happy with either of us. Immediately checked Amazon and purchased these. Saved me from sleeping in the dog bed. They are great. Help keep coffee warm and keep things out.

Big fan. If you work in an office and are a slow drinker/always getting interrupted then This is for YOU! But use on top of any mug - works great!

I use these in conjunction with a Mr Coffee mug warmer. They're honestly great. The suction power is also good but with warm beverages there is no suction because of the constantly expanding air on the inside. I've not yet tried them with cold beverages but I imagine the suction is better with those. They're great for keeping bugs out and heat in.

We also have porcelain cup covers but I needed one more so I bought this set. Initially, I was skeptical of using a silicon cover, wasn't sure if it would work as well as the porcelain one - but it's doing even better. The advantage is that it creates a suction contact which the porcelain one didn't. It's also easy to put or lift due to the pointy handle on top. Should it last a good time, I find it a very useful convenince to have.

4-pack is a great value, they work well, and are nice to have around the house in case you need to plug a sink or bath tub drain OR steep your tea ;)
