So cute and exactly what I had in mind, except it does not stay on. There is no adhesive, and it doesn’t click in place. It basically sits on top, so if you grab the bottle by the handle, it falls off every time. Kind of useless. Seller was great at communicating, and it is a cute idea, just didn’t execute as I needed it to.

Happy with my choice of flip straw for driving purposes! My daughter scared me about a video she saw with a metal straw puncturing the roof of someone’s mouth in a sudden breaking incident. I was convinced on the flip straw choice for the car trips

Doesn’t fit taunt and falls off. Cute product but useless. Also, one of mine was broken. Not seller fault, I’m sure during shipping. Wasn’t packaged with any protective wrapping.

I absolutely love this tumbler! My ice didn’t melt until after my 16 hour shift ended! I absolutely recommend this tumbler!
