B Box Lunchbox - Confetti

b.box Large Lunchbox – Roomy, Flexible and Easy to Pack

Need a lunchbox with enough room for a full school day? The b.box Large Lunchbox has a generous 2 litre or 8-cup capacity, making it a wonderful choice for primary school children, bigger appetites and anyone who enjoys plenty of variety.

As a mum who has packed many school lunches, I love that this lunchbox gives you room for everyday favourites without needing lots of separate containers. There’s space for sandwiches, rolls, wraps, fruit, yoghurt, dips and snacks — all neatly organised inside one practical lunchbox.

Is the Large b.box Lunchbox the Right Size?

The large or original b.box Lunchbox is best suited to:

• Primary school children with an average to larger appetite

• Children who carry their lunch and snacks together

• Bigger eaters who find smaller bento boxes too restrictive

• Teens and adults wanting a roomy, divided lunchbox

• Families who prefer fewer loose containers in the school bag

For younger children, smaller appetites or children who take morning tea separately, the b.box Mini Lunchbox may be a better fit.

Why Parents Love the b.box Large Lunchbox

• Generous 8-cup capacity: Plenty of room for lunch, fruit and snacks.

• Fits everyday foods: Pack sandwiches, rolls, wraps and larger pieces of fruit without squeezing everything into tiny spaces.

• Flexible whole-fruit compartment: The clever silicone flexi seal stretches around taller foods and whole fruit such as apples.

• Adjustable divider: Slide or remove the divider to change the compartment size depending on what you are packing.

• Two individually sealed compartments: Suitable for thicker wet foods such as yoghurt, dips and custard.*

• Built-in cooling feature: A removable gel cooler sits beneath the sandwich compartment.

• Easy-open latch and carry handle: Designed to support independent lunchtime routines.

• Removable seals: The seals can be removed for more thorough cleaning.

• Replacement parts available: Replace selected parts instead of needing to purchase an entirely new lunchbox.

What Fits Inside a b.box Large Lunchbox?

With approximately 2 litres or 8 cups of capacity, there is room to pack a satisfying combination of foods, including:

• Sandwiches, wraps and bread rolls

• Whole or sliced fruit

• Yoghurt, custard and thick dips*

• Crackers, vegetables and cheese

• Home-baked snacks

• A balanced lunch plus morning-tea snacks

The adjustable divider makes it easy to change the layout as your child’s preferences and appetite change.

Which Insulated Lunch Bag Fits the Large b.box Lunchbox?

Choosing the correct bag is important because the large b.box Lunchbox will not fit comfortably inside every insulated lunch bag.

It fits beautifully inside the b.box Flexi Insulated Lunch Bag. For families wanting space for both the large lunchbox and a separate snack box, we recommend choosing one of our compatible larger insulated bags or a ready-made b.box lunchbox bundle, where we have already checked that every item works together.

Frequently Asked Questions

Is the b.box Large Lunchbox the original b.box size?

Yes. The large lunchbox is also commonly called the original b.box Lunchbox. It holds approximately 2 litres or 8 cups of food.

Is it suitable for Prep?

It can be a great Prep lunchbox for children with an average to larger appetite or those who carry all their food in one box. For a smaller eater, the b.box Mini Lunchbox paired with a separate snack box may feel less overwhelming.

Is the entire lunchbox leakproof?

No. Two specially sealed compartments are designed for thicker wet foods such as yoghurt, dips and custard. The remaining sections are not intended to hold liquids.*

Does it fit a whole apple?

The flexible silicone fruit seal is designed to stretch around taller foods and many whole pieces of fruit. Fit will depend on the individual size of the fruit.

Does it include an ice pack?

The lunchbox includes a small removable gel cooler beneath the sandwich compartment. For Australian school days, we still recommend placing the lunchbox inside a quality insulated bag with an additional ice pack.

Can I personalise my b.box Lunchbox?

Yes! Selected b.box lunchboxes can be personalised by Coastal Kidswear, helping children recognise their lunchbox and reducing the chance of it becoming lost at kindy, school or daycare.
