Straw Toppers for Stanley Cup, Cute Straw Cover Cap Compatible with 20 30 40 Oz Tumbler and Water Bottles, 6 8 10mm Straws Accessories, 2Pcs Silicone Rose Flower for Women Girls Friends Gift (Pink)

It fits my 40 oz Stanley perfectly! I only drink water out of mine so I can't say if it will stain or not with other drinks. I've recieved so many compliments on how cute it is whenever I take it with me to shopping /walking. Excellent price. The color is very true to the pictures online. Absolutely no water comes out of the straw. It hasn't snapped off and I've had it for weeks/months now. Easy to clean if you own a straw cleaner. Highly reccomend for straw protection with style.

Super cute very functional and fit very well. Great value may get a few more not heavy or gaudy very dainty

Great quality. I’ve been using these for months and they haven’t broken. They fit Stanley straws perfectly, and I feel like a lot of straw covers are hard to fit on Stanley’s, even when they claim they will. These go on easily, and are super cute!

nice touch during the day. very cute. leak proof. fit my bigger cups. good value

Perfect! It’s cover and cute. I should have had one before I found a bug in my cup! The only way in was through the straw. That won’t happen again!

Stem part is a little thinner than expected, but fits well and are very pretty

Works great to keep little things from flying into mouth if straw, and keep it from spilling when moving around.. Absolutely amazing product! Wish I could afford more right now!

This is so *stinkin'* cute. Matches my cup and fits perfectly. Love it!
