The Kaally Bento 4 Plus is a 304-grade stainless steel lunchbox for bigger kids and bigger appetites — four compartments, nearly a litre of space, and none of the plastic. The LFGB-certified silicone seal keeps every compartment leak-proof and pops off for a proper clean, while the silicone-grip latch means kids from 3+ can open and close it without help.
Why Families Choose This Stainless Steel Bento Box
Most kids lunchboxes that promise leak-proof compartments manage it with plastic — plastic walls, plastic dividers, plastic lids. This stainless steel bento box does it with 304 (18/8) steel and an LFGB-certified silicone seal, so nothing your child’s food touches is plastic. The four compartments hold a proper school lunch: a 445mL main, two 200mL-plus sides, and a 99mL treat well — 964mL all up, with every compartment sealed from its neighbours so yoghurt stays out of the crackers.
The latch matters more than it looks: stainless steel wire with a colour-matched silicone grip that kids from about three can open and close on their own — no waiting for a teacher at lunch time. And because the seal pops out and everything is dishwasher safe (top rack), there are no corners for yesterday’s lunch to hide in.
For smaller appetites or daycare snack breaks, the Kaally Snack Box uses the same steel-and-silicone build in a two-compartment size. Add an Insulated Food Jar 350mL for days when lunch is something hot, and a Kaally Glass Bottle 500mL to round out a plastic-free lunch kit.
