By packing up your own food you can avoid unhealthy fast food joints or restaurants which is better for your health and energy levels too. Enjoy your food warm or cold with our advanced thermal lunch box which now features a heat release valve for ultimate convenience. Lunch at the caf down the road, the food van outside the office, and the school canteen can all be expensive choices. Lunches at cafes, vans, and schools can be overpriced choices, so take your favorite meal with you, or last night's leftovers. Set of blue, green, orange. Blue, Black, Gray, Green, Pink. Dishwasher safe.
