The Sunflower Lunchbox is a little solar-powered appliance that heats and cools food items according to your desires.

The flowery design of the box has collapsible petals used to trap solar energy, which is then stored in its internal battery. With a quick push of a button, you can heat up or cool down your cuisine within the individual boxes of the Sunflower Lunchbox. With this item, you'll barely have to use the microwave or fridge again!
