Perfect fit for Stanley cups straw. Easy to put on and take off

These straw cap is super cute. It keeps bugs out and with the other parts it becomes leak proof.

Adorable straw covers- love them! Durable and a good fit on the Stanley 40 oz straw.

These things were cute but hard to put on the Stanley cup. Had to take out the straw and force on. I started a return but I will keep them now!

I get a lot of compliments on these little guys! Even got some friends to get some of their own! Seriously functional, great to bring to the work place without worrying about setting my Stanley somewhere and worrying about getting anything on my straw or contaminating it in anyway. It’s an adorable piece of mind.

Grandkids love them for their Stanley's. Gave one as a gift too.

I got these to keep bugs out of my straws and as soon as they came in I kept finding bugs on my lids so definitely a good purchase!

10mm is perfect fit the 40oz!!! Not flimsy. Super cute clouds.

Looks great, crisp lines and dye on the cloud face, good quality product. I'm excited to try them on my Stanley

This does not fit my Stanley cup 30 oz. The hole in the cloud is so small can’t even force it or anything. Do not waste your money on this.False advertising.

These do not fit Stanley cup straws. Don’t waste your money.
