The PlanetBox has small bento-like compartments that keep foods separate. There’s a designated space for everything that you could think of. Their website explains that you can pack most foods in the PlanetBox compartments without fear of leakage. But for juicy or liquidy items, they suggest the separate stainless steel containers (called Dippers) that have a seal. They also offer magnets that can be used to decorate the outside of the lunchbox. You can also purchase a carrying case for the PlanetBox. Interested? More details available on their site.
