B.Box Large Lunchbox

The B.Box Large Lunchbox is the full-size step up from the original B.Box, a bigger container built for primary school-aged kids who have outgrown smaller portions and need a lunchbox that handles a complete meal without multiple separate containers.

It keeps everything that made the original B.Box popular: the leak-proof silicone seals, the flexi fruit holder, the adjustable divider, and scales it all up for bigger appetites, longer school days, and meals that don't fit into a snackbox-sized space.

What the B.Box Large Lunchbox Includes

Every B.Box Large Lunchbox in this collection comes with a built-in gel cooler pack that sits beneath the removable sandwich tray, adding passive cooling without needing a separate ice brick.

• Spacious main compartment fits a full sandwich, bagel, or roll with the tray in place. Remove it, and the same space handles pasta, salads or larger meals.

• Adjustable custom divider slides across to resize compartments depending on what you're packing, or removes entirely to fit a whole banana or large wrap.

• Flexi whole fruit holder stretches around whole fruits, an apple, a mandarin, a pear, so there's no need to cut fruit into smaller pieces.

• Leak-proof silicone seals handle wet foods like watermelon, yoghurt and dips without leaking into the main compartment.

Not Fully Insulated, But Cooler Than You'd Expect

The B.Box lunch box large is not a fully insulated box, but the included gel cooler pack keeps the internal temperature noticeably lower than an uninsulated container for several hours. For full insulation, pair it with a B.Box Insulated Lunch Bag.

Designs in This Collection

Available in licensed character editions, Frozen, Batman and The Little Mermaid, as well as solid colourways including Lemon Twist and Ocean Breeze. All designs are BPA-free, PVC-free, phthalate-free and hand wash only to preserve the print and leak-proof seals.

Personalise It: Engraving on Your B.Box Large Lunchbox

Want to make your child's lunchbox unmistakably theirs? BentoBliss offers personalised engraving on select B.Box lunchboxes, available in two ways:

• Engraving on the silicone seal: the name or initials are engraved onto the silicone seal under the lid. Hence, the personalisation stays with the box and isn't affected by handwashing over time.

• Engraving on the lunchbox lid: the name or initials are engraved directly onto the lid, giving a clear, visible personalisation that's easy to spot in a busy school bag or classroom tub bin.

Both options work well for primary school kids managing their own lunchbox day to day. Check the individual product page for which engraving option applies to that item, or browse the full Personalised Engraving range.
