Leak-resistant food-grade silicone seal
Functional and stable — chosen for safety, not convenience

Replace plastic once.
It will scratch — steel does. It won't stain, warp, or hold yesterday's smell.

A 304 stainless steel lunch box, a steel lid, a removable divider, and one food-grade silicone seal. Two materials, and we name them both. Here is why we use a silicone seal.

Dimensions: 170 x 120 x 60 mm
Capacity: 800 ml
Weight: 275 g
Material: 304 food-grade stainless steel
Dishwasher safe: Yes
Leak resistance: Leak-resistant. Clip-locking lids with a food-grade silicone seal. We say resistant, not proof — the seal is a consumable, and we would rather you knew that than find out.

Dishwasher safe. For a deeper clean, remove the silicone seal and rinse it separately. Dry completely before storing. Avoid abrasive cleaners to preserve the surface finish. Not suitable for the microwave — here is how to heat food without one.

Order before 12:00 on a weekday and it leaves our warehouse the same day. Everything ships tracked, so you can see where it is. Delivery after that: 1–3 business days in the Netherlands, 3–7 in the rest of the EU.

Silicone seal lifted half out of the lid channel of a rectangular stainless steel lunch box lid

Nothing to hide under the lid

Lift the ring out of its channel and you are holding the complete materials list: a 304 stainless steel lid and one food-grade silicone seal. The seal comes out for cleaning and presses back in seconds — and when it wears, you replace the seal, not the box. No plastic touches your food. You can check that with your thumb.

Rectangular stainless steel lunch box in everyday use

A system that covers everything. Without thinking about it.

Batch cooking on Sunday. Leftovers on Monday. A snack in your bag on Tuesday. Our sets are built around the way people actually use containers — not the way they imagine they will. Sizes that stack, and two materials we name on the page.

The material

Two materials. Both named.

304 stainless steel

Body, lid and the removable divider. The same 304 in every container we make, whatever the size.

One food-grade silicone seal

Removable. Washable. We'll sell you a spare for as long as you own it.

Nothing else

No coatings, no liners, no "composite of ingredients." If a third material ever appears, it goes on the page before it goes in the box.

And what it won't do

It doesn't go in the microwave. You can't see through it. It's heavier than plastic. If that matters more, buy something else.

Why it matters

You already read the label.
Then it goes in a plastic box.

You cook. You check ingredients. Then the last step of that chain is a container you've never once looked at. Not carelessness — habit.

We're not here to tell you plastic is dangerous. Nobody can tell you that honestly. We're here because"nobody knows yet"isn't a good enough answer for the thing your dinner sits in for three days.

Straight answers

Before you buy

No. Steel never goes in a microwave — not ours, not anybody's. It is the one real trade-off in owning steel, and we would rather you knew it before you bought than after. There is a short guide on the site for reheating without one.

Yes, all of it. Lids on the top rack. Let everything dry fully before you put it away — steel doesn't mind water, but water left standing leaves lime marks.

Leak-resistant, and we won't say leakproof. Upright in a bag or a fridge it holds. On its side with soup in it, we wouldn't bet on it. The seal is silicone and silicone wears out — which is why we sell spares instead of pretending it won't.

Yes. Steel doesn't go brittle in the cold and it won't crack the way glass can. Leave a couple of centimetres of headspace so the food has room to expand as it freezes.

No. Steel is non-porous, so garlic, curry and fish don't stay behind the way they do in plastic. The one place odour can linger is the silicone seal — take it out and wash it separately now and then.

No. Two materials, and we name them both: 304 food-grade stainless steel, and one food-grade silicone seal. No coating, no liner, no third material.

Yes. Steel scratches — a fork, a brush and a dishwasher rack all leave marks eventually. The difference is what a scratch means. In plastic it is somewhere for oils and colour to settle. In steel it is cosmetic and nothing else.
