The Stojo bottle is shape-shifting wonder that holds 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. The silicone on our Jelly collection is see thru! 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.
