For years I bought lunch gear the way most parents do: whatever looked good on the shelf that week. A container here, a drink bottle there, none of it actually designed to work together. The result was a cupboard full of mismatched lids and a morning routine that felt like solving a puzzle with half the pieces missing.
The fix wasn't a better container. It was a system, with real sizes behind every piece of it, and it's the whole logic behind our bento range and lunch bags today.
The Actual Problem
It was never really about finding "the best lunchbox." It was about three separate food moments in a school day, fruit break, recess and lunch, each needing its own right-sized container, all of which then needed to fit into one lunch bag, which then needed to fit into one pocket of the backpack, alongside the homework folder, the library bag and the water bottle. One good lunch box doesn't solve a problem that's actually about how everything fits together.
Getting the sizing right for each of those three moments is what actually saved me time, roughly half an hour every single morning once I had it dialled in, because I wasn't second-guessing portions, repacking a spill, or scraping a barely touched lunch into the bin each afternoon. Less stress, and we all got to school and work on time.
What "Everything Has a Place" Actually Means
- Three right-sized containers, one for each break, matched to real capacities, not guesswork, so nothing's oversized or wasted (the exact sizes are below)
- One lunch bag that all three actually fit inside
- One backpack pocket sized for the lunch bag, homework folder, water bottle and library bag together
- A magnetic hat clip on the outside, so it's visually checked in three seconds, not searched for
Every piece is designed against the others, not on its own. That's the difference between a system and a pile of containers that happen to be the same brand.
The Actual Container Sizes We Used
This is the part most lunch box guides skip. Sizes aren't one-size-fits-all, they change as your kid grows and eats more, so here's exactly what we used, and when.
Early Kindy Through the First Couple of Years of School
-
Fruit break, 100ml: just big enough to be eaten in time before the bell. We used the Silicone Mini Snack Boxes (5 Pack).
-
Recess, 550ml: large enough for a morning tea style snack, a handful of chips, a muffin, a cupcake, a lamington, or whole fruit, though cut-up fruit came home eaten about 99 percent more often than whole pieces. We used the Flexi Snack Box.
-
Lunch, 800ml: a four-compartment bento to divide protein, carb, fruit and veg portions. We used the Quad Bento.
-
On colder days: we'd swap to a larger bento that an insulated food jar actually fits inside, one less thing to carry, and it meant warm foods like rice, pasta or mini meatballs could go in too. Our pick for this is the Duo Combo, a 1350ml four-compartment bento that comes with a 200ml insulated food jar, sized so each portion fits just right.
As He Got Older and Needed More Fill
-
Morning fruit break, 550ml: the Flexi Snack Box.
-
Recess, 800ml: the Quad Bento.
-
Lunch, 800ml to 1200ml: we'd alternate depending on what we were packing that day:
- An 800ml Large Insulated Food Jar for a proper hot lunch.
- The 1200ml stainless steel Core Bento, genuinely versatile since the divider can be removed to switch between a three-compartment bento and one large compartment.
- Or for a mix of hot and cold food in the same lunch, the Duo Combo again, its 1350ml four-compartment bento plus 200ml insulated food jar covers both in one system.
What Other Families Tell Us
A lot of parents tell us they've moved to our three-container system and gone with our size recommendations, and the pattern that comes back most is simple: the portions are right, and food is actually coming home eaten instead of binned.
One mum of three primary-school-aged kids told us she wished she'd found this system when her eldest first started school. She'd wasted money on the wrong containers, wasted money over-packing food that came home untouched, and said the system made her whole routine noticeably less stressful. Her kids now take an interest in helping pack their own lunches, and each child has their own colour across all their bento pieces, so everyone instantly knows whose is whose.
Hearing that from another parent meant a lot, because it's exactly the problem I was solving for in the first place. It took real time and a lot of trial and error to get our own sizing right, and it's still the thing that saves me about half an hour every school morning.
Why This Matters More on the Bad Mornings
On a calm morning, almost any gear works fine. It's the rushed ones, the mornings you're one forgotten item from being late, where a system earns its keep. When every container is already the right size for the food going in it, packing stops being a decision and becomes a routine, which is exactly what a stressed 7.15am needs.

FAQs
What is the Spixal lunch system?
A coordinated set of right-sized containers, a lunch bag and a backpack, all designed to fit together, so packing school lunches becomes one job instead of ten separate decisions.
Why use three containers instead of one big lunchbox?
Three right-sized containers mean each food moment, fruit break, recess and lunch, gets exactly what it needs, and if one is dropped or opened awkwardly, the rest of the day's food is still fine.
What size lunch containers do I actually need for school?
It depends on age and appetite. In the early kindy years we used a 100ml container for fruit break, 550ml for recess and an 800ml four-compartment bento for lunch, moving up to a 200ml insulated food jar for warm food on cold days. As our son got older that became 550ml for fruit break, 800ml for recess and 800ml to 1200ml for lunch, depending on whether it was a hot, cold, or combination meal.
