Protect your lunch with metal. ECOlunchbox’s stainless steel Three-in-One bento (nesting containers) box has three compartments, an upper and lower food container matched with a smaller ECOlunchpod snack container. The design keeps food items separate, nicely packed in sturdy metal boxes. Food can be reheated in the metal containers over a camp stove or a medium-heat oven. The three piece set of boxes have a combined carry capacity of 900 ml (31 fl. oz) and weigh 450 g (16 oz).
