Backpack tumble test: backpacks get tossed, wedged, and flipped. That’s the real leak test. Flimsy tubs pop open; zipper bags seep. A stainless snack container with a silicone gasket at the lid keeps portions contained while food touches only steel, no plasticky smell, no mystery residue. It’s sized for real snacks and shrugs off drops, so the container lasts longer than the fad lunch gear.
Reasons
- Plastic-free food contact (18/8 stainless interior; silicone only at the lid seal)
- Leak-resistant by design (great for juicy fruit, yogurt, or dips)
- Kid-friendly open/close (soft gasket, no brittle clips)
- Right-size portions (8–12 oz fit lunch bags and bento slots)
- Dishwasher-safe steel; lids air-dry quickly
- Reusable = less waste and better long-term value
When to skip: For hot soups or big meal portions, use a stainless lunch container or insulated jar with a sealing lid.

FAQ
Are stainless snack containers really leak-proof?
They’re leak-resistant, not leak-proof. A silicone gasket on the lid helps with juicy fruit or dips, but avoid tipping them upside down with liquids.
Is silicone safe for food contact in these containers?
Yes, our policy (PF-Silicone) allows silicone when it’s just the lid gasket or seal. Food touches only stainless steel inside the cup.
What size should I pick for kids’ lunches?
Most run 8–12 ounces. That’s enough for fruit, crackers, or yogurt without taking over the lunch bag. The smaller 8-oz is easy for younger kids.
Can I wash them in the dishwasher?
Yes. Stainless cups are dishwasher-safe; silicone lids can go on the top rack and air-dry quickly.
Do they dent or rust over time?
Drops may cause small dents, but 18/8 stainless steel resists rust. Rinse promptly after acidic foods (like citrus) to keep them looking good.
