I love this little straw. It folds up to fit in even my smallest purse and the rubber tip doesn't hurt my teeth. It's easy to carry, use, and wash. It comes with a rounds case to keep it in and also a little tool used to keep it clean. I use it all the time when we go out the eat or even at home. I absolutely love that it folds up and has a case because I have some other ones that get all dirty being in my bags. This way, I don'th have to clean the straw before I even use it.
