If you want a lunch box that truly doesn’t leak, look for a stainless body with a steel lid and a silicone gasket—no plastic touching food, clip closures, and dishwasher-safe parts. That’s the bar we used to choose our winner.
🏆 Blockhütte Stainless Steel Lunch Box I 27oz
PF-Silicone = metal/ceramic drink path; gasket/sipper is silicone. What’s our PF scale?
Why we like it: This is the everyday leak-proof you can toss in a bag without fear. The stainless body pairs with a steel lid and silicone gasket so dressings and sauces stay put. It’s dishwasher-safe, wipes clean fast, and the compact, lunch-bag-friendly shape makes portioning simple without plastic touching food. For work, school, picnics, or commute meals, it’s the durable, reusable upgrade that cuts single-use waste while keeping your food fresh and organized on the go.
- Best for: salads with dressing, leftovers with sauces, commute or school lunches.
- Specs: ≈27 oz; 18/8 stainless box + steel lid with silicone seal; clip closure; dishwasher-safe.
- Care tip: After washing, remove the gasket to dry fully, then re-seat it evenly for a tight seal. (Not microwave-safe.)
Size note: Also comes in Compact (≈21 oz) and XL (≈41 oz, big appetite). Choose your size on the product page.
