The vivo mio foldable wine bottle is a new unique way of getting your wine from one place to another. I like how you don’t have to worry about any glass bottles being broken while being transported from one location to another. The material it’s made out of is a nice thick plastic that you can fold up when your not using. It’s simple to use and store your wine. The hard part is pouring you wine into the plastic bottles without making a mess. Other than that it works great!
