OmieBox uses two types of insulation in order to store hot & cold food together. At the heart of the design is a powerful vacuum insulated thermos. It’s made of two walls of stainless steel with the air sucked out in between so heat can’t escape. It can keep food warm for up to 6 hours, perfect for hot lunch. Food is kept cool through OmieBox’s double walled, air insulated tray. Air is an excellent insulator (think styrofoam or double pane windows - both use air insulation).
