BTYHAOS Straw Covers, Dust Proof Straw Toppers Fit Stanley 30 40oz Tumbler

Cute little flower silicone straw caps. There are 6 random colors and they fit my Hydroflask. Not overly easy to put on the cap one-handed because the straw is flexible and wants to bend when you try, but it can be done. Or you can just use two hands while the mug is sitting on a table or counter to make it easier. I think having a cap helps the ice to last longer, plus the obvious thing, to keep it clean. I wish the colors were a little closer of a match to my cup, but they work and are still cute. I would recommend if you want something inexpensive to help keep your liquids cold and the straw clean.

Exactly what I needed for my Stanley cup and it’s really cute. I use the black one and it stays on pretty well. And personally easy for me to clean. I also work in an area where dust particles can get everywhere so it’s nice cover.

Very cute works great I use them on my Stanley Cups. Keeps the bugs off my straw.

I have been searching for some reasonably priced straw caps for my cup, which is not a Stanley lol. I came across this brand since our was a great value for the money. These silicone straw caps fit my 40oz Owala cup perfectly. The colors are very pretty and complements the cup as well. They are versatile and extremely easy to use. They appear to be quite durable and quality. Highly recommend giving these a try if you're on a budget like me.

They are so cute and pretty but it doesn’t fit my owala straw that well. It is loose and if I turn it upside down it falls off. The band only fits the thick part of the straw that has the logo or else it would also be loose. The top the actual cap is loose and doesn’t fit snug the way I was expecting. At least it’s cute and pretty to look at and at least it covers my straw opening to prevent germs from people’s bad breath being near my bottle but I’m just sad it didn’t fit snugly.

They are adorable. They are compatible and stay securely on the straw of my Owala water bottle with no problem and prevent leaking from the straw. And of course the price is right. I would buy them again.

Perfect for my Stanley. Fit well and matched exactly to the color I needed I’ve been using for weeks no issues

If have water bottles with exposed straw these are great. They go on easy, compatible with my Hydro flask (similar style as the Stanley cup), love the colors. Easy to clean, I popped them in the dishwasher before using.
