Choose the size for tonight.
And keep the same container for everything that comes after.
Cook tonight's portion in a Loopware container, keep tomorrow's in the same one, and reheat it straight from the fridge or freezer. One container, one thing to wash.
Cook, keep and reheat in the same container

Cook two portions. Eat one.
The 1.0L holds two portions: dinner tonight, lunch tomorrow, without moving it to another box.
Batch it once, eat it all week.
Loosen the lid while it's cold, then heat until piping hot. On gas, use a heat diffuser.
Pan, dish and tub in one.
It cooks, it serves, it stores. The pan you'd have scrubbed never comes out of the cupboard.
Small cupboard? One slot.
Empty containers nest inside each other, same size or mixed. The lids stack on their own.

Lid on, about 20 x 13 x 7 cm. It weighs about 240 g. The finished wall is 0.4 mm steel.

Lid on, about 23 x 16 x 8 cm. It weighs about 305 to 330 g, depending on the lid style.

Put water in the 1.6L and set the 1.0L inside it with the food. On the hob on a low heat, the water steams the food in the inner container. Keep water in the outer container: never heat it empty. See the nested steaming method
“The small one sits inside the big one. Now it's a steamer.”
Put water in the 1.6L and set the 1.0L inside it with the food. On the hob on a low heat, the water steams the food in the inner container. Keep water in the outer one: never heat it empty. That's why the Starter Set is one of each.
Body and lid are 304 stainless steel: no plastic, no silicone seal, nothing but steel touching your food. SGS, an independent lab, held a test liquid in it at 100 °C for four hours, three times over, and screened for 22 metals. None was detected, and we test every production batch. At the end of its life it goes back into steel, as good as new.

How many portions does each size hold?
The 1.0L holds two portions, the 1.6L three. How much fits depends on how compact the food is.
Does it work on induction?
Flat 304 sheet isn't magnetic, but deep-drawing the container from one sheet makes it weakly magnetic, enough for most induction hobs to pick it up. Why stainless steel
Can it go in an air fryer?
Lid on, the 1.0L is about 20 x 13 cm and the 1.6L about 23 x 16 cm. Leave room at the sides so you can lift the container out.
Why not the microwave?
Steel is a poor microwave material. Metal reflects microwaves, so in a steel box the food only takes in energy through the open top: it heats slowly and wastes power. Some steel boxes are made microwavable with smoothed edges and specially curved corners (World Stainless Association), and that's what you see sold as "microwave-safe". However, we make Loopware containers to last for years, and steel can dent; sparking can start at sharp edges, rims and dents. We don't take a risk that can grow with age lightly. The hob or oven does it better.
Can I carry soup in it?
Keep it level. It's spill-resistant, not leakproof or airtight, so don't carry loose liquids in a bag.
How do I use the lid when cooking?
Steel expands as it heats, so a lid pressed on can grip tighter just when the container is too hot to hold firmly. The lid's overhang is your grip. The cooking guide
