12oz stemless wine tumbler lid replacement (4 Pack)，2.9 inch diameter spill proof，for Sivaphe and Corkcicle Double-wall Stainless Steel Travel Coffee Mug

I had been looking everywhere for replacement lids for my cup. I was very happy that I found these and they fit my cup perfectly. I use my cup for hot tea and the lids hold up very well to the heat. I have placed my cup and lid in the dishwasher and it came out clean so I would say they are heat tolerant. The quality of them is good. I would definitely buy more and recommend to anyone that is looking for replacement lids.

There's no slide meaning no ucky' build up of under the slide crud. These are definitely the way to go. They fit perfectly and hold up well with repeated dishwasher cleaning . I'll buy them again.

Needed a replacement lid on my favorite cup my daughter got me for Christmas. I have a tall custom made cup (like the kind that people sell at craft fairs). These fit perfectly! Just measure your existing lid, and make sure it's the same size.

Did not fit the Corkicle coffee cup as the ad stated it would.

Nice appearance and thickness. Good on leakage and seal but not so much on durability. Overall, it is a nice product.

These work perfectly with the stemless wine glass stainless steel cups that we use for coffee or cold drinks.

These lids seal and fit great but they are not easy to clean. Stuff gets under the sliding lid and there is no way to get to it. I have soaked them, tried to pop the piece off but I can't get it. I am going to throw them away and buy something where I can remove the sliding piece to clean it. It's too bad because if it wasn't for that these are great.

Very sturdy heavy duty plastic with an excellent o-ring seal

Product description in the images says 81mm across where I measured it to be 77mm.

I’m UK based, so only caved in to buy this 4pk of lids after a month of buying (and returning) many similar lids on Amazon that did not fit my cup. So far I cannot locate any 12oz lids in UK, but do not regret the purchase of this from USA. The lid is made of excellent quality, fits tightly and securely, and washes easily. I’ve had no staining from drinking tea, red drinks or hot chocolate as you can see in the picture. My husband and I both have these types of thermal travel cups so these lids were excellent value!

I thought I bought the right size from the measurement. There are so many sizes. It unfortunately didnt fit. I was able to use the seals on my old lids but they (the old lids) are a bit broken

These are to big for the 12oz tumbler
