PureLunchBox Airtight Bento is a practical lunch box made of food-grade stainless steel, with a silicone gasket at the edge of the top lid. It closes that way tightly, but is not 100% waterproof. With the two separate compartments, you can keep food separate — and thanks to the silicone seal in the upper compartment, you can safely take salad or dinner leftovers into the lunch box. The PureLunchBox Airtight Bento is distinguished by its simple classic design and its durability. Material: Food grade stainless steel and silicone Size: 130 x 115 mm. Volume: Holds a total of 1125 ml. Upper compartment 550 ml. Bottom compartment 575 ml. Care instructions: The lunch box is dishwasher safe. Free from: Endocrine disruptors, BPA, chemicals and heavy metals
