On cold mornings I stopped packing two separate things and started reaching for the Duo. A 1350ml bento with all four compartments sealed individually, plus the 200ml food jar clipped in alongside it, meant I could send rice, pasta or mini meatballs to school still warm, right next to the cut fruit and crackers, without adding a second container to the bag. One less thing to carry, one less thing to forget.
It turned out to solve a second problem too. If your kid is just starting daycare, kindy or their first year of school, the biggest lunchbox hurdle usually isn't what goes in it, it's whether they can actually open it themselves. That's exactly the gap the Duo bento box fills as well, and why it's ended up working for us at both ends of primary school, not just the youngest kids.
The Duo pairs the 1350ml four-compartment bento with the small 200ml insulated food jar, and both pieces use an easy-opening design made specifically for kids who are still building the fine motor skills a screw-top lid asks for.
What's Actually in the Set
-
The bento: 4 fixed compartments (they don't reconfigure) in a 1350ml bento, each one sealing individually, so it's fully leakproof. A single clip closure keeps it easy to open, and there's enough capacity for a proper serve, not just a toddler-sized portion.
-
The food jar: A 200ml insulated jar with a gasket, 1-clip lift-open lid, instead of the usual screw top, so little hands can get in without a fight.
Why Fixed Compartments Matter Here
Unlike the reconfigurable pieces in our range, the Duo's compartments are fixed in place. For younger kids, that's a feature, not a limitation: the same layout every day means less decision fatigue for you, and every section sealing individually means nothing leaks into anything else, however the bag gets tossed around.
It Actually Passes the Little Hands Test
One mum in our Lunch Club told us her preschool teacher pulled her aside at pickup. Out of every lunchbox that teacher sees across the whole preschool, the Duo was the one that impressed her most, because she'd watched the child open both the bento and the food jar completely on their own, no help needed. She said she was going to start recommending it to other mums.
That's the actual test this set is built for, not easy to open in theory, but easy enough that a preschooler can manage it solo on a busy morning.
Warm Lunches, Sorted
The included food jar means warm lunches don't need a second product. Pack it with pasta, soup, or last night's dinner reheated, and the gasket lid holds the heat properly, not just warm-ish by recess.
"Packed at 7am, still warm at lunch at 12:30, the kids love it!"
Who the Duo Suits Best
- Kids starting daycare, kindy or their first year of school
- Kids who need consistent, fixed compartments rather than a reconfigurable layout
- Families wanting a bento and warm food jar in one purchase
- Anyone who needs full leakproof sealing, no exceptions
- Older primary kids too, the 1350ml capacity holds a proper-sized serve, and packing hot and cold food side by side in one set works just as well for a hungry eight-year-old as it does for a preschooler

FAQs
What age is the Duo bento box best for?
It's designed for younger kids, daycare, kindy and early primary years, thanks to its easy 1-clip opening and gasket lift-lid food jar, but the 1350ml capacity means plenty of families keep using it right through primary school.
Is the Duo bento box leakproof?
Yes. All 4 compartments are fixed and seal individually, so it's fully leakproof, unlike the reconfigurable pieces in the range.
Can the Duo food jar keep food warm until lunchtime?
Yes. One Spixal Lunch Club mum packed it at 7am and it was still warm at lunch at 12:30. The 200ml insulated jar is designed to hold heat properly, not just take the chill off.
Is the Duo bento box good for older kids, not just toddlers?
Yes. While the easy-open design was built with little hands in mind, the 1350ml capacity and the ability to pack hot and cold food side by side in one set makes it just as useful for older primary kids with bigger appetites.
