Iced Coffee Silicone Ring for Cold Beverages,2 Pack Reusable Silicone Lid for 30oz Stainless Steel Tumbler,for YETI,RTIC,BJPKPK,for Cup Mouth Diameter 3.9-4 inch (Marble)

This is the best addition to a cup that I already have, this helps my drinks that I buy anywhere to fit well and stay cold all day. Will not promise leak proof but it’s works amazing to keep your drinks cold. Super easy to put on the top of your metal cup and then just put the new coffee cup inside.

I drink my iced coffee slow, and hate when it melts all and/or gets condensation all over my desk. I saw ads for another brand of cup that came with gaskets like these, but I already have so many cups! It was great to be able to buy just the ring, pop it on and use it immediately. I've already had several people ask me where to buy them, definitely a must have for me!

Fits great.

Fit onto 30oz yeti tumbler perfectly. Worked for a Dunkin medium & a McDonald's large mcafe so far. Much better option for someone who already has a lot of tumblers/prefers a specific type, & price was great.

This slipped right onto my Ozark Trail 30 ounce tumbler with ease, but also did not feel loose or easy to accidentally slip off. I've tested it out with several iced coffees from local shops, and it seems to work the best with the classic medium/standard sized cups. A large coffee also fits into it with no issues, but the top inch or so might be above the cup if it's a really large drink.Best part, is that it definitely seems to keep drinks cold. Had a drink for hours at the office with plenty of ice by the end of the day. So adding it on your tumbler is a great way to keep drinks cold, and also cut down the condensation.

I got this to use with my 24oz RTIC, but it doesn’t fit. It is too big. This has a wide 4” opening made for the big 40oz insulated mugs with the handle. It works well with those. Easy to use, just drop the coffee cup into the opening and the finger tabs keep it from sliding thru. Good for doubling up when you don’t want to cross-contaminate. Allows for the insulating of the mug while keeping the experience of drinking out of the to-go cup.The molding is done well, no defects. Colors look like green camo.

The material and design combined keeps drinks in tact. Nice design but once your drink is in a tumbler, it’s to very easy getting it back out if you are needing to without squeezing your cup and popping a lid off in the act. Good value for the two pack. Maybe a design to remove a little easier would be cool.
