Steel. All the way to the lid.
Every lid in every set is 304 stainless steel. So is every bottle cap.
That is unusual. Almost every container you can buy — steel or glass, cheap or expensive — closes with polypropylene. Chilly’s, Stanley, Hydro Flask, Mepal, IKEA, Bentgo. And every glass container sold in the Netherlands, without exception. Glass solved the box and forgot the lid. See the whole category, lid by lid.
Two materials. Both named.
304 food-grade stainless steel, and one food-grade silicone seal. That is the entire list, across every piece in every set.
The seal is the only part that wears out — silicone loses its spring after a few years of dishwasher cycles. So we sell you a new one for a few euros, for as long as you own the product, rather than expecting you to replace the container. Replacement seals.
Which set?
- School Lunch Set — lunch box, snack pot, bottle. A school day, sorted.
- Workday Essentials — lunch, a side, and the day’s water.
- Starter Set — three containers that cover most of what you store. The right first step.
- Pro Set — four sizes that stack. Built for Sunday batch cooking.
- Complete Set — everything. One material, the whole kitchen, one decision.
And what steel won’t do
It doesn’t go in the microwave. You can’t see through it. It’s heavier than plastic. If those things matter more to you than what your food touches, buy something else — with our blessing.
