Food Jar Features & FAQs

You asked, we’ve answered. If you’re curious about how our Food Jars work, what they’re made of, or how to choose the right size for your needs—this guide is for you.

What Are They Made Of?

Our Food Jar bases are made from premium vacuum-insulated stainless steel (18/8 and 304 grade), which helps keep food hot or cold for longer. The finish is scratch- and dent-resistant—great for little hands and daily use. The lids are made from BPA-free polypropylene and feature an easy-grip silicone band for easy opening.

What Size Should I Choose?

We offer two sizes depending on what you’re packing:

• Mini Food Jar (200ml): Ideal for smaller serves like yoghurt, snacks, or breakfast on the go.

• Regular Food Jar (400ml): Great for a full meal—perfect for soups, pasta, or leftovers.

Both are insulated to keep food at the right temperature for hours.

Do Bumpers Fit?

Yes. Our Large Bumpers are designed to fit both the Mini and Regular Food Jars. They provide added grip and protection, plus a fun pop of colour.

Do Food Jars Fit in Montii Lunch Boxes?

The Mini Food Jar fits perfectly into the largest compartment of our Feast Lunch Box. It’s a handy way to send hot or cold food alongside your usual lunchbox items.
