Coffee Mug Lid(3.15"Inner Diameter,3.43"Outer Diameter), KSENDALO Thick Eco Reusable Silicone Travel Mug Lids, Silicone Cup Cover, black（1pc)

Case fits perfectly!

My wife and I absolutely love these lids. We run our own ceramic business and sell handthrown 16oz travel mugs and we rely on these lids for all of pieces and they fit perfectly! We test every piece and there has never been a single leak or a lid popping off even if you tip it completely upside down. Additionally, with all of the travel mugs being handthrown on a pottery wheel, the sizes can vary slightly at the rim, but even with the variance, they work perfectly! We’ve been relying on these lids for over a year now and have placed multiple orders and have never been disappointed. They have definitely found a repeat customer in us!

Definitely a solid fit. My only complaint is the kids have a distinctive smell to them, even after they have washed. So that's a little inconvenient when drinking. But hey no bugs in my mug at the campsite.

They work. They do exactly what I wanted them to do. At Knotts Berry Farm, you get a drink pass for like 36.99, gets you free 12oz drinks every 15 mins. But no lid. So I got these and im so excited. No issues with plastic smell or taste. Like 100% so happy with these for the cold drinks

Tops for hand thrown cups. Need to adjust for clay shrinkage. I am hoping that this product will fit my cups well.

Was looking for a replacement lid for an old travel mug. This one fits snugly and works great, except for the smell! It's awful to drink coffee and have the smell of rubber take over.I'll have to find a way to remove the smell, because otherwise the lid is great.

I have so many travel mugs and a lot of the time, the lids either get lost or they start cracking. I found these because of the amount you get in one package and really like them. They fit the majority of my mugs and are pretty sturdy without leaking. Sometimes if they are not tight enough, they leak, so make sure they are on securely. The only issue that I do not like is sometimes they maintain the smell of the dish detergent and you can smell that when drink from the mug. I tried different way to fix that, but nothing worked so far. Other than that, these are a great find.

They fit very loosely and won’t stay on. Very dangerous with coffee.
