How we evaluated it
Why we chose it What put it on our list
- Food touches steel and silicone only. The body is 18/8 stainless steel (certified 90% post-consumer recycled, per the maker) and the lid is food-grade silicone.
- Klean Kanteen lists it as BPA-, BPS-, BPF- and lead-free, and plastic free if you use it without the divider.
- Use limits are written down: dishwasher and freezer safe, and oven reheating only, up to 20 minutes at 350°F (177°C) with the lid off.
- The lid is leakproof, and the box is covered by a Strong as Steel Lifetime Limited Warranty.
Trade-offs What to weigh before you buy
- No independent testing is published. The material and safety claims are the maker’s own.
- The divider may be plastic: the “plastic free” statement applies when you use the box without it.
- Oven use is limited to reheating, and the page does not say where the box is made.
- The page does not say whether replacement lids are sold.
What to know Details worth knowing first
Steel and silicone are the other way to keep plastic away from food. This box is stainless steel with a silicone lid, sized for a lunch. Our guide to reducing microplastics recommends exactly that swap, and BPA-free is not safe explains why a “BPA-free” plastic label is not enough.
We have no test report to show you. The materials are simple enough that the maker’s description is reasonable to rely on, but it is the maker’s description. The one detail to watch is the divider: Klean Kanteen’s own “plastic free” line applies only without it.
Quality & testing How it measures up against our checklist
| What we checked | What we found |
|---|---|
| Glass or steel where food touches Maker’s claim | 18/8 stainless steel body, “certified 90% post-consumer recycled”. The page does not name the certifier of the recycled content. |
| Lids and seals you can name Maker’s claim | A leakproof, food-grade silicone lid. The divider’s material is not stated. |
| Written heat limits Maker’s claim | Dishwasher and freezer safe. Oven reheating only, up to 20 minutes at 350°F (177°C), lid removed. |
| Replaceable parts Not verified | Not stated on the page we read. |
| BPA, BPS, BPF and lead Maker’s claim | “BPA-, BPS-, BPF- and lead-free”, stated by the maker. |
| Company certification Maker’s claim | The site shows “Certified B Corp”. We did not check B Lab’s directory, and B Corp certifies the company, not this product. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.

Alternatives Other options to compare
- WECK Mold Jars Glass jars with glass lids and natural rubber rings. Heavier and breakable, so better for the fridge than a lunch bag.
- Glass containers with silicone lids Same idea in glass: you can see what is inside, and nothing plastic touches the food. Check the lid material and heat limits.
