b.box Large Lunchbox – Sugar Plum | 2L Bento Lunch Box

Looking for a lunchbox with enough room for a whole sandwich, whole fruit and plenty of variety without needing lots of separate containers?

The b.box Large Lunchbox in Sugar Plum is a generous 2L bento lunchbox, holding approximately 8 cups of food. It's a brilliant choice for school-aged children, bigger appetites or anyone who likes plenty of choice throughout the day.

The clever layout gives you the flexibility to pack everything from a whole sandwich, wraps and bread rolls to fruit, yoghurt, dips and snacks — while the removable sandwich tray gives you extra depth when you need room for larger foods, pasta or salads.

Who Is the b.box Large Best For?

We recommend choosing your child's lunchbox based on their appetite and school routine rather than age alone.

The b.box Large is a great option for:

• Bigger or growing appetites

• Primary school lunches

• Full school days

• Children who enjoy plenty of food variety

• Kids who prefer lunch and snacks packed together

• Families wanting space for whole sandwiches, rolls, wraps and fruit

• Children who regularly need more food than a smaller bento can hold

A child starting Prep doesn't automatically need a Large lunchbox. Some smaller eaters are much happier with a Mini, while other Prep children need the extra capacity of the Large.

For smaller appetites, take a look at our b.box Mini Lunchboxes.

What Can You Fit in a b.box Large Lunchbox?

This is one of the reasons the Large b.box is such a popular school lunchbox.

Depending on what your child likes to eat, you can pack:

• A whole sandwich plus fruit and snacks

• Bread rolls or bagels

• Wraps

• Whole fruit

• Yoghurt, purée or dips in the sealed compartments

• Pasta or salad with the sandwich tray removed

• A whole banana by adjusting or removing the divider

• Plenty of smaller snacks and finger foods

For children who have Crunch & Sip, fruit break or morning tea separately, pairing the Large with a b.box Snack Box can work beautifully.

Should I Choose the b.box Large or Mini?

The biggest difference is capacity.

b.box Large: 2L / approximately 8 cups
Best for bigger appetites, full school days and children wanting plenty of variety.

b.box Mini: 1L / approximately 4 cups
Best for smaller appetites, compact lunches and children who prefer less food at one time.

Rather than choosing purely by your child's age, think about how much they actually eat and whether morning tea is packed separately.

Want to Add a Snack Box?

For bigger eaters or children who have a separate fruit or morning-tea break, adding a b.box Snack Box is one of our favourite combinations.

It means lunch can stay packed neatly in the Large while fruit or morning tea is easy to grab separately.
