The Stojo bottle is shape-shifting wonder that holds a whopping 20 oz of liquid when full, and collapses into a polite sphere when empty. This is the perfect on-the-go travel partner. Customer's can collapse it before going through airport security until they're ready to fill at a water station - saves space and money! It's a new water bottle without the bulk. This comes in our collapsed packaging which shows our product in its smallest form, about the size of a grapefruit. This packaging type is perfect for small space storage and gives customers a quick glance on the collapsibility benefit of a Stojo bottle.
