MontiiCo Review: Lunch Boxes, Food Jars & Accessories Tested

If you've spent any time in an Australian school car park, you've seen a MontiiCo lunch box. The brand has become one of the most recognisable names in kids' lunchware, known for its pastel colour palettes and interlocking bento-style trays. But recognisable doesn't always mean right for your family, so here's an honest look at what MontiiCo actually gets right, where it falls short, and which pieces are worth adding to your rotation.

At BentoBliss, we stock a curated range of MontiiCo food jars, lunch boxes, and snack accessories. This review covers what we carry, how each product performs day to day, and where MontiiCo sits against other brands in our range like Oasis and Bentgo.

What Is MontiiCo?

MontiiCo is an Australian-designed lunchware brand built around mix-and-match bento systems. Instead of one fixed lunch box, most of the range works as interchangeable bases, lids, and inserts, so families can build a set that suits their child's appetite and school routine. The line-up runs from full bento lunch boxes down to insulated food jars and snack trays, all sharing the same colourways, which makes it easy to build a matching set.

MontiiCo Bento Feast Lunch Box Review

The MontiiCo Bento Feast Lunch Box is the brand's flagship, and it is the one most parents ask about first.

What we like:

• Multiple compartments keep food separated, which matters if your child is fussy about flavours touching

• The latch system is sturdy enough to survive being tossed into a school bag

• Available in six colourways, so siblings can have their own without mix-ups at pickup

What to know before buying:

• It is a bigger box, so it is better suited to primary-aged kids with a solid appetite than toddlers

• Not insulated on its own, so hot food needs to go in a separate jar

Priced from $45.95, it sits in the mid-range for bento boxes and pairs well with the food jars below for a complete hot-and-cold lunch system.

MontiiCo Insulated Food Jar Review (400ml)

This is the product we get asked about most, and it is worth the attention.

The MontiiCo Insulated Food Jar holds 400ml and is built from double-wall vacuum-insulated stainless steel (18/8 and 304 grade). MontiiCo rates it to keep food warm for up to 8 hours and cold for up to 7 hours, which comfortably covers a full school day if you preheat it properly.

What we like:

• Every part, including the lid and silicone seal, is dishwasher-safe. No hand-scrubbing the seal every night.

• The lid has an easy-grip silicone band, which genuinely helps younger kids open it without help

• At 280g, it is light enough for a lunch bag without adding much bulk

• 100% lead- and BPA-free

What to know before buying:

• Preheating matters. Rinse it with boiling water and let it sit for a few minutes before adding hot food, or the 8-hour claim will fall short

• The 400ml capacity is a proper serve for a primary-aged child but may be tight for a hungry teenager

It comes in four colourways: Apple, Floss, Lilac, and Navy, priced from $34.95.

MontiiCo Insulated Mini Food Jar Review (200ml)

For younger kids or smaller appetites, the MontiiCo Insulated Mini Food Jar shares the same build quality in a 200ml size. It is the better pick for preschool and kindy lunches, where a full 400ml serve would go home half-eaten. Priced from $29.95, and available in the same four colourways as the regular jar.

MontiiCo Insulated Lunch Pot and Snack Pot Review

Sitting between the food jar and a full lunch box, the MontiiCo Insulated Lunch Pot (from $32.95) and MontiiCo Insulated Snack Pot (from $31.95) are wider and shallower than the standard jar, which makes them a better shape for pasta, rice dishes, or chunkier foods that are awkward to spoon out of a narrow jar. Both come in Bubblegum, Cream, Lilac, Mojito and more.

MontiiCo Snack Lunch Box and Snack Tray Review

For snack-only days, the MontiiCo Snack Lunch Box (from $24.95) and the MontiiCo Silicone Snack Tray (from $8.95) round out the range. The silicone tray in particular is one of our best sellers for parents who want portioned snacks without buying a full new lunch box, and at under $9, it is an easy add-on to any order.

A Note on MontiiCo Drink Bottles and Lunch Bags

If you have searched for a MontiiCo drink bottle or MontiiCo lunch bag, it is worth knowing upfront that BentoBliss does not currently stock MontiiCo's bottle or bag ranges. Our MontiiCo range is focused on food jars, lunch boxes, and snack accessories.

For insulated drink bottles, our most popular alternatives are the B.Box Insulated Drink Bottle range and Oasis bottles and tumblers, both of which offer similar or longer heat retention (up to 15 hours cold on some B.Box models) and dishwasher-safe designs.

For insulated lunch bags, browse our full Insulated Lunch Bags collection, including the Sachi Crossbody Insulated Bottle Bag if you want something that carries a bottle and daily essentials in one.

Is MontiiCo Worth It?

For families who want a coordinated, colour-matched lunch system with genuinely reliable insulation on the food jars, MontiiCo earns its popularity. The food jars in particular hold up to the brand's hot and cold claims when preheated properly, and the dishwasher-safe design saves real time on school nights. Where it falls short is coverage: if you need a drink bottle or lunch bag to match, you will need to pair it with another brand in our range.

Frequently Asked Questions

Is MontiiCo dishwasher safe? 

Yes. Every MontiiCo food jar and lunch pot we stock, including the base, lid, and silicone seal, is dishwasher safe.

How long does the MontiiCo food jar keep food hot? 

Up to 8 hours when preheated with boiling water first. Without preheating, expect shorter retention.

The 200ml Mini Food Jar is the better fit for toddlers and preschoolers. The 400ml jar suits primary-aged kids and up.

Does BentoBliss sell MontiiCo drink bottles? 

Not currently. Our MontiiCo range covers food jars, lunch boxes, and snack accessories. For insulated bottles, see our B.Box and Oasis ranges instead.
