Years. We guarantee ten — and we won’t advertise past our own warranty, which is why you won’t see “lifetime” anywhere on this page.
Food-grade 304 stainless has no real wear-out mechanism under normal kitchen use. It doesn’t have a coating to peel, a plastic that fatigues, or a surface that clouds. It’s the same material commercial kitchens have leaned on for decades precisely because it doesn’t give out.
What actually ages a steel container: almost nothing. It can pick up cosmetic scratches or minor dents, but those don’t affect whether it’s safe or usable. A brushed finish hides them well.
The one part that has a shorter life: the silicone lid seal. Seals are consumable — over years they can loosen or pick up odors. The fix is simple: rinse it separately now and then, dry it fully, and replace just the seal if it ever stops sealing. The container itself keeps going. This is why the guarantee covers the steel and not the seal — one of them is a ten-year object and one of them isn’t, and we’d rather sell you a €4.95 ring than a new box.
How to get the full lifespan: don’t leave it sitting wet for long stretches (304 resists rust but isn’t rust-proof if abused), don’t let salty or briny liquid stand in it for weeks, skip harsh abrasives that scratch, and hand-dry the seal. That’s the entire maintenance list.
This is the quiet appeal of steel. You buy it, and then it just keeps being a container — through years of lunches, more than one phase of life, sometimes more than one kid. The material outlasts the reasons you bought it.
Food should be stored without doubt.
