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.

The material

Two materials. Both named.

304 stainless steel

Every surface your food touches is 304. Where a product uses another grade — the bottle's outer shell is 201 — we name it on the page.

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.

Glass is right at home. Steel is what survives the day.

If it never leaves the kitchen, glass is a fine choice. It's clear, it's inert, it goes in the oven. But the moment it goes into a bag, glass is the wrong material. And its lid was always plastic anyway.

Replace it once.

Then stop thinking about it.
