5PCS 0.4in/10mm Diameter Silicone Straw Covers Cap Compatible with Stanley 20 30&40 Oz Cup, Straw Toppers for Stanley 40 Oz Tumbler with Handle, Dust-Proof Straw Caps - Molandiy Colors

Love this set, I gifted 3 and kept one because it is so convenient and had to try it out. Will definitely buy more! Easy to clean and functions well and keeps water from leaking.

Whomever came up with the straw cover idea must be a humble genius. It's a cool looking must have if you use a travel tumbler with a straw. It keeps outside pollutants from getting into your beverage, which is extremely important for me since I work at a very large hospital and all sorts of germs are floating around. Other than being adorable I got these 5 straw cover at an awesome promotional price of like $2.50!!! I couldn't not buy it!

Works great on my Yeti staw rambler. Super cute 😍

Really cute nice made but to small for my straw

These are so cute! They fit the straw of my Stanley perfectly and seal it up nice and tight. It doesn’t leak if I knock it over. And the extra little blingy chain for the handle of the cup is super cute! I’ve had numerous compliments and comments on it. Especially when people know me and know I have three different colors of French Bulldogs. I love these little straw covers and recommend them. I don’t know yet how durable they are going to be but I do know how cute they are and that I have had the one cover on my straw for well over a month now and it’s showing no signs of leaking. So that’s great. I would buy these again if I ever need to.

I loved these, they're super cute and are easy to get on and off of the straw. I would buy them again.

So cute and fit easily.

I purchased these to keep bugs and other contaminants from coming in contact with my straw and it does just that. They are cute & were a great price too!
