This is for the times when you want to drink a wine (Concerts, Picnics, Hiking, Camping, Boating, Tailgating, relaxing at the park) but you just don’t want to take a glass bottle with you because it can break and shatter. It is a foldable, reusable, disposable, 100% recyclable, leakproof wine bottle . After you are done just fold it. Just look at the review, people are loving it. It will hold a full bottle of your favorite wine.
