Insulated Food Jar 350mL

The Kaally Insulated Food Jar (350mL) is a 304 (18/8) stainless steel food storage container available in Green, Pink, and Purple. Designed for school lunches, daycare, and on-the-go family meals, it keeps food hot or cold for up to 4–5 hours. The LFGB-certified silicone seal keeps everything leak-proof and covers the internal plastic, so food only contacts steel and silicone.

Why Parents Choose This Kids Food Thermos

A kids food thermos has one job: lunch that’s still properly hot (or properly cold) hours after it left the kitchen. This one does it with vacuum-insulated 304 (18/8) stainless steel — up to 4–5 hours of heat or chill — and no plastic in contact with the food. The LFGB-certified silicone seal covers the lid’s internal plastic, so everything your child eats has only touched steel and silicone.

At 350mL it holds a genuine school-lunch serve — soup, fried rice, mac and cheese, leftovers — and the leak-proof lid means it rides in the school bag upright or not. For toddler portions there’s the Insulated Food Jar 250mL; for cold food days the Kaally Snack Box and Kaally Bento 4 Plus use the same steel-and-silicone build. A quick pre-warm — boiling water in for a couple of minutes, out, then food in — keeps lunch hotter for longer.
