Silicone Spill Stopper Set

Works great on sealing out dust and dirt, or any leaks if spilled over. The seal is so airtight that I have to pull the straw the whole way to the stopper, otherwise my water will shoot out of the straw. Afterwards, slowly push your straw to the bottom of your cup, and cap.

These are the perfect straw caps for my Hydroflask straws. A Hydro flask straws are different than regular straws and are a little bit bigger, these caps fit on the top of the straw perfectly.

These work perfectly for my yeti cup! No leaks at all!!

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.

Fits my yeti straw perfectly

Stops major leaking- easy to use, I still store my water bottle upright.

works nice, keep the straw clean, easy to install, nice color and durability

The airtight plug doesn't allow any liquid to pass through the straw. It fits my YETI water bottle great, but not worth it for me to recommend it tp others. The straw needs air to be able to drink. I love that it doesn't leak, but took it off because I couldn't get anything through the straw. The flower straw cover is really cute, but by the 3rd day, the stem came off. Disappointed the the product didn't work well for me. The quality could be better, but the silicone straw cover fit well & is durable. I still use it, but it now has np dyem so I don't lose it.

Cundo cierras el termo hay que tener cuidado por que se sale el liquidonpor el popote, ya que queda hermético y no sale aire
