Juice boxes haven't changed too much. They are typically rectangle tetrapacks and are somewhat boring. Why not take it away from rectangles and create something more exciting? I created a form that would be fun for kids, but also solves the issue of juice boxes falling over or being crushed. The new juice box is more stable and more fun to drink out of.
