Super cute. Definitely leak proof. But, I’m a school bus driver. Last thing I want is a watered down warm drink when I finally can take a sip. Does not keep cold. Ice melted in less than 2 hrs. It was 105 outside… very hot in the bus. I did an experiment. Couple hrs before bed I filled it my ice water and fav flavor packet. I jumped in the pool for an hr after dark. Then went to bed. Up way too early at 4 am and ice was gone and water was nasty again. Strongly do not recommend.

Perfect tumbler - love that you can close the straw

Great idea but when you open the auction ouahes out the liquid and it squrts ya.

It doesn’t keep the cold inside it

Love them. Love the way the straw folds up and is covered

Great product with the ability to lock straw inside.

I love that the cup fits in my cup holder. The straw system is wonderful.

Saw this in the club and immediately bought it for the lemon design. I love that the straw is retractable to protect against germs over those straw covers. Very happy with my purchase.

These stainless steel tumblers are awesome! They do NOT leak, which is great! Completely worth the purchase

Sturdy, easy to clean.
