I’ve been using stackable stainless steel lunchboxes for my kids for about 3 years. They’ve only needed one lunchbox each in this entire time, and apart from superficial scratches the lunchboxes are undamaged. I love them because they are cleanable (I mean, completely! no mould or lingering smells in these lunchboxes 😁), extremely durable, lightweight, and plastic-free.  The only down-side is my kids’ lunchboxes are a bit small… 🤔

…And then I discovered these Bentō Ninja lunchboxes! These lunchboxes are grown-up size. And therefore suitable for school-age kids too.  The other awesome feature of the Bentō Ninja lunchboxes is they have clamps for both the top and bottom tiers, so you can use the top tier separately for a smaller lunch.  My almost-3-year-old can open and close it easily, including the small rectangular container that comes with it.

Although it isn’t leakproof, you can buy the silicone-lidded leakproof containers separately here, and both the small and large sizes fit inside the top tier of the standard bentō box, or top and bottom tiers of the deep bentō box.

Dishwasher safe in the top rack. Do not use in the microwave!

Warranty information:

    OMgoddess! What a wonderful find! This lunch box is perfect for all your foodie needs with your little one, fitting everything for you and them you could need. I also use mine for takeaway sushi and indian its the perfect size. Love knowing this can be reused a bazillion times and when it finally falls apart it can be recycled.
