Our product, Luncheon Tiffin is tiffin which keeps the food at the ideal warm temperature. Our  tiffin works on the mechanism of solar cooker. We have fixed a glass on the top which collects all the sunrays and passes on to the food and makes it warm. We have painted the tiffin black as black is a good conductor of heat. This product maintains the food temperature at an eatable temperature so the people can enjoy their lunch.
