Packing plastic-free lunches is simpler when the snack box itself is stainless steel. Paired with a silicone gasket, it keeps portions tidy without plastic food contact—and it survives the school year.
1) Plastic-free food contact
18/8 stainless is inert and easy to clean. With a silicone gasket in the lid, food touches steel or silicone, not plastic.
2) Leak-resistant by design
A snug seal helps with juicy fruit, yogurt, or dips—fewer lunchbox messes and backpack cleanups.
3) Kid-friendly and durable
Brushed steel resists cracks and odors. Soft silicone lids are easy to open for small hands.
4) Right-size portions
The 8–12 oz range fits snacks without bulk, and nests neatly in most lunch bags and bento boxes.
5) Dishwasher-safe cleanup
A dishwasher-safe stainless container saves weeknight time; silicone lids air-dry quickly.
6) Less waste than disposables
Reusable steel replaces piles of single-use baggies and flimsy tubs.
7) Better long-term value
Stainless survives drops and daily use—lower cost per use than replacing cracked plastic.
