Misen Misenware Stainless Storage Set
304 stainless containers with silicone-rimmed tempered glass lids - a rare all-steel storage set that's genuinely microwave-safe, with no plastic in the food path. Currently a Kickstarter (ships Oct 2026).
The verdict: Silicone only
Food touches only 304 stainless steel and glass. The containers are 1.0 mm 304 stainless, and the universal lid is tempered glass with a silicone rim that forms the leakproof seal (and a silicone steam vent). The only non-metal, non-glass material anywhere is that silicone gasket, which is the norm for any leakproof lid - so it lands at silicone-only. Notably it also skips the plastic snap lid that compromises almost every other storage set. Misen markets it on "zero microplastics"; the one nuance is that the seal is silicone, not that there's any plastic.
What it's made of
| Part | Material | Food contact |
|---|---|---|
| container body 1.0 mm-thick 304 stainless; oven-safe to 932°F/500°C, and microwave-safe (rounded corners, tested to 1100W) - unusual for steel | Stainless Steel 304 / 18-8 | Yes primary |
| lid (glass) tempered glass; oven-safe to ~400-450°F, microwave-safe with the steam vent open (not freezer-to-oven safe) | Tempered Glass | Yes incidental |
| lid rim / seal + steam vent silicone rim forms the leakproof seal; the only non-glass/steel material | Silicone | Yes seal |
A nesting stainless-steel food storage system in three self-stacking sizes - Small (~2.95 cups / 700 ml), Medium (~4.64 cups / 1,100 ml), and Large (~6.34 cups / 1,500 ml) - that share one universal silicone-rimmed tempered glass lid, so there are no mismatched container-and-lid pairs. The 18-piece Mixed set is an assortment of the three sizes with matching lids. The steel bodies go oven (to 500°C), grill, freezer, and dishwasher, and - unusually for metal - the microwave, thanks to thick walls and rounded corners; the glass lid is microwave-safe with its steam vent open. Volume measurements are engraved on the inner walls.
Pros
- All-steel body with a glass lid and silicone seal - no plastic in the food path, and no plastic snap lid
- Genuinely microwave-safe stainless (lab-tested to 1100W), plus oven/grill/freezer/dishwasher
- One universal lid fits all three sizes; containers self-nest to save space
- Leakproof (passes upside-down/sideways tests with water, oil, and tomato sauce)
Cons
- Not shipping until ~October 2026 - crowdfunding pledge, not a finished retail product yet
- Expensive for a storage set
- Glass lid isn't freezer-to-oven safe and tops out around 400-450°F (remove or vent it above that)
- Silicone seal (not for strict silicone-avoiders)
Notes
- Sold as a Kickstarter late-pledge; also offered in 12-piece and 6-piece sets that use the same containers
- Do not use in 1200W or 915 MHz microwaves, and keep the containers from touching the microwave's metal walls/rack (can spark)
Common questions
Does the Misen Misenware Stainless Storage Set have plastic in it?
No petroleum plastic touches your food. On the Misen Misenware Stainless Storage Set, the lid rim / seal + steam vent is silicone, and the rest of the food path is stainless steel and tempered glass.

Part by part, the Misen Misenware Stainless Storage Set is: container body — stainless steel; lid (glass) — tempered glass; lid rim / seal + steam vent — silicone.
Does the Misen Misenware Stainless Storage Set have silicone in it?
Yes — the lid rim / seal + steam vent is silicone on the Misen Misenware Stainless Storage Set. It is a seal rather than a surface your food sits against, which is stainless steel and tempered glass.
Is the Misen Misenware Stainless Storage Set BPA-free?
No plastic touches your food on the Misen Misenware Stainless Storage Set — the food path is stainless steel, tempered glass and silicone — so BPA, which comes from polycarbonate and epoxy plastics, is not in play here.
