EcoStack 3-Tier Wheat Straw Bento Box

Three tiers instead of three compartments. The EcoStack stacks its 900 ml capacity vertically, so a main, a side and a dessert each get their own sealed box rather than sharing one tray, and you unstack only what you are eating. It keeps a footprint small enough for a crowded office fridge or a rucksack side pocket, and it stands upright on a desk without wobbling.

The material is wheat straw fibre blended with food-grade polymer: a by-product of the wheat harvest that would otherwise be burned or discarded, pressed into something rigid, light and pleasantly matt to hold. It carries no odours from yesterday's curry, does not stain from tomato sauce the way cheap plastic does, and can be reheated in the microwave with the lids removed before going through the dishwasher.

A clip secures the tiers together for transport, and the seal on each level means a dressing or a yoghurt travels in the same bag as a sandwich without incident. It suits school lunches, commutes, picnics and long journeys equally well. Let hot food cool a little before sealing so steam does not condense inside, and check the temperature of reheated food before serving it to a child.
