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.

This stopper fits the straw perfectly and works as described.

I bought it for my 40 “ yeti tumbler top the quality seems durable. The little rubber fit perfectly on the top and it actually does as advertised it prevents spills. Good product for the price.

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.

Game changer for my straw. This helps prevent leaks, keeps bugs/germs away from where my mouth touches the straw, and is simple looking for those of us who don’t want animals or other objects on our straws.

This keeps everything out and is really useful when I forget it's on my cup and I put just the tip in my mouth

They fit my yeti perfectly, no spills, and durable.

The whole idea is great. Seals almost as well as a properly sealed tumbler. Be carefull how you fit the lid once the gasket is in place, you may get your beverage shot into your eye!
