Silicone Spill Stopper Compatible with YETI Straw Cup, Mug Tumbler Accessories Including 2 Straw Cover Topper Cap, 2 Leak Proof Stopper

The media could not be loaded. I just wish Yeti would make a complete product in the first place. Great mugs, cups, and ramblers but poor lids with straws.From the included picture, you can see the spacing in between the straw and lid. With the circular lid attachment, it completely seals the open space. I was really impressed with the quality of these little silicone rings and caps. I would fully recommend this to anyone wanting to leak proof their lids.

What a great find! These spill stoppers are a perfect fit on my (Yeti) travel cup, and look nice with their neutral color (clearish opaque white) will work with any color. They work really well too, I accidentally tested their effectiveness and fitment almost as quickly as I put them on my cup. Super easy to install & remove, plus, with the two pack one can always be in use and easily traded out for cleaning.(LUOLAO Silicone Spill Stopper)

These items work very well, up to a point.It really depends on what you’re drinking.I have found that they are indeed very airtight, and do prevent leaks. However, they are so airtight that when you close the lid the liquid just shoots up the straw. You have to be very careful when putting the lid on and very slowly push the straw down.The first time I used this, it was with sparkling water. I cannot believe the mess it made when I pushed the straw in, so I have learned to do just what I advised above. Other than that, these work pretty good.

It fits on the straw, and looks so cute. So cheap, but very good quality. My daughter wants some too, will buy for her next time.

Almost works too well. Using on my Yeti straw lid it prevents the odd spill around the straw, however it seals so well it creates a vacuum in the cup when putting the lid on with the straw and shoots liquid up the straw like a rocket. Doesn't bother me at all though, just be mindful when using them. Love these will repurchase when I need more.

Fit perfectly and at a good price for a yeti accessory

It does keep drink from leaking but, fill your cup and put on the lid and you now get all the liquid volcanoing (I know not a word) out of the straw all over everything. And since there is no air hole there is a suction issue when drinking.

This little flower works so well! I feel better keeping my straw covered and feel like it stays cleaner when it’s sitting on my desk or when carrying it out in public.
