## Description

desertcart.com: AICMEI 2 Replacement Lids for 20oz Stainless Steel Tumbler Lids-Replaces Only Covers With a Top Diameter of 3.4 inches（Bottom Diameter of 3.23 inches） : Home & Kitchen

Review: This lid size was a rare find so it’s an overall good buy ! - My lids came with one broken in which case it would have been nice to have a spare but the good one (black slider) fit my cup perfectly. My cup was 3.3 inches (83 mm) with my calipers , not too tight or loose, just right ! A ruler in mm though should get you a close idea of your size cup. The slider was “sticky” as many had mentioned which was irritating and my temporary fix was to put castor oil on the inner side of the slide which made a nice smooth action and I didn’t particularly mind a few drops of organic castor oil in my coffee, no particular taste but a little messy, needed to be redone every new cup full to stay smooth however. One day a month or so in it occurred to me to examine the slides more closely and in so doing it occurred to me that when they formed the slider to the lid slot with heat(not a correct supposition)there was no way to leave appropriate clearance for smooth action. Then it came to mind that a thin scraping along the travel of the slider on the lid part would give me the few thousands of an inch needed for silky action ! This was easily accomplished with a razor knife with the blade sharpened with the bur on the side that would scrape as I used it right handedly . A few light trips with the blade sideways bringing up some thin curls of plastic and then sliding the slider each way to get each end of the track did (a part of the trick) (Skip this step until you try the side track first) Then I noticed as well that there was a slight catch in the inside of the track also which I smoothed out with the same method with the point of the knife down and the sideways motion. In retrospect, on further inspection, I should have noticed that the slots are larger at the ends which allows the slider to be removed (after running under hot water to soften the slider plastic) for cleaning by squeezing the tabs inward to remove it at either end of it’s travel in the slots. Then tentatively just scrape the humps (or just the larger one to start) in the middle which keep the lid from falling shut when you tip it up to drink. It didn’t take me long to figure out that simply pressing one’s nose and/or lips against the slider after opening was an easy way to keep it open for drinking and better yet it falls shut after you’ve gotten your sip/drink , Auto closure! There’s a delicate point to be mastered when scraping the middle hump on the track if you’d prefer the usual action ! Was nice to learn that one can remove the slider to clean under it though, even the expensive Swig lid, as near as I can tell, can’t be cleaned under the slider. So all that said , it may not be needed to do anything except shave the middle hump (larger on one side). Still, I think I would rather have it too loose than too tight. This was discovered by taking a bit too much off the hump and possibly on the top of the lid as well causing to it being now too loose to stay put ! This lid also fit my wife’s expensive cup (Swig) for which we had just unfortunately spent around 20$ for a new lid ! Also I had another favorite cup that this lid fits as well so it seems to be a common size but just a silly mm either way on our other cups gets either too snug or too loose for a perfect fit! After much shopping, this lid size was very rare so I consider it an overall good buy! I assume the usual case would be two good lids, we can always hope anyway !
Review: Check the pictures. These were perfect!!! - Perfect fit thanks to the detailed description with the pictures. I literally needed 2 odor these lids. They original lids did break easy but the cups are so special, it's worth it. Might buy more to have on hand. Nice plastic material, light lid with a good seal. There is no color to them, perfectly clear.

## Features

- Caution! The size of the lid has a top diameter of 8.6cm/3.4 inches and a bottom diameter of 8.2cm/3.23 inches, please understand that there may be an error of about 0.02 due to the different ways of measurement. So this lid simply can only replace the same size 20 ounce lid. In order to avoid you buy the wrong size lid, please measure the size of your original lid to see if it is the same size as the one we are selling before you buy it. Thanks! Measurement You can refer to our video the way we measure.
- The LIDS are not universal. Please check whether the size of your old lid is the same as the size of the LIDS we sell before purchasing to avoid buying an unsuitable one. Not all 30oz LIDS are the same. Please check the size carefully and purchase with caution!
- SPLASH-PROOF：Our pack of 2 non-flip lids features a leak and spill proof design, the flat bottom lid is lined with a silicone gasket around the edge and features a sliding mechanism and tighter snap design, the leak and spill proof feature cannot be ignored, so you don't have to worry about spills and leaks, especially when filling hot beverages or when driving. It prevents splashes and large spills when flipping the cup over.
- HIGH-QUALITY MATERIALS：Our replacement cup lid features double seal technology to support the temperature of your drink, whether hot or cold, you can enjoy your favorite beverage.Made of high-quality raw materials, can be used for a long time, In addition, it is very easy and convenient to clean, hand wash, or dishwasher .
- EASY TO OPEN AND CLOSE：Switch sliding cover design, easy to use. The hole on the top of the cup can be used directly or with a straw. The sliding cover design prevents you from touching your nose while drinking water.
- Aset of 2, you can use one for yourself, the others can be given to your loved ones, or your dear family and friends, or you can keep it as a spare.But I think it's good for friends who drive, because it has a splash-proof function that keeps the liquid inside the water cup in the car from splashing out.So if you usually have a lot of driving, give it to yourself, or to your friends who drive around.
- When your insulated mug is filled with your favourite drink, cover it with our lid and place it in your car where you keep your mug, it will cover the mug very securely and will not let the liquid spill. If you have any questions or dissatisfaction with our products, you can contact us, we will do our best to serve you.

## Questions & Answers

**Q: Will this fit the Titan 30 oz tumbler?**
A: I have two 30 oz tumblers, one is generic & the other is RTIC. They each have measured inside diameter openings of 3 3/4 inches. The lids fit both perfectly. If your tumbler is similar you should be in luck, probably. For me, at this the price, the risk was worth taking given the alternative was having useless cups.

**Q: Will these lids fit a 24 oz bubba tumbler?**
A: No, they fit 30 and 32 oz cups

**Q: I need to return this item, lids did not fit. What do I need to do to return item?**
A: Contact Amazon if purchased from them and get a return authorization. Then return to Amazon.

**Q: Do these fit the great american 24 oz stainless steel tumblers?**
A: Yes

### ⭐⭐⭐⭐⭐ Replacement lid fits perfectly.
*by B***G on January 22, 2026*

I have a favorite thermally insulated mug which I travel with a log and use as home as well. I accidentally dropped the lid on the floor and broke it. I needed a replacement lid so that I could travel without spilling in the car and also when I watch tv when I accidentally tip over the mug by accident. I measured the outside diameter of the inside lip of the mug and searched using this criteria and came up with the perfect lid replacement. See pictures.
