The WeeSprout Kids Thermos is the upgrade every school lunchbox needs. Made from ultra-durable 18/8 stainless steel, this vacuum-insulated thermos is designed to keep hot foods warm and cold foods cool for hours — no microwaves or cafeteria lines required.
The airtight twist lid seals inside the thermos to lock in temperature and prevent leaks. Plus, a copper-coated inner wall helps reflect heat (or cold) back toward your child’s food for optimal insulation. The wide-mouth opening makes it easy for kids to eat directly from the thermos, and the kid-friendly top handle gives them independence at lunchtime.
Whether it’s soup, pasta, yogurt, or leftovers from last night’s dinner, this thermos keeps food fresh and ready to enjoy — no soggy lunchboxes or wasted meals!
