I was wanting to minimise plastic use in our household especially around food, so I was looking at stainless lunchboxes including planet box and other international brands. I settled on BentoNinja Ultimate Ninja Pack for a few reasons. It seemed that the configuration of the boxes would be more flexible. Because there were no tiny compartments built in, which seems great for little people but not so much with kids 6+. We mix it up and do sandwiches one day with the full box, then just send the shallow box section with snacks and partner with a thermos for hot lunch. The set came with lots of different leakproof containers so I can pack leaky cut fruit like kiwifruit and it doesn't get all over everything else. This was a huge plus, as many other boxes are not leakproof and you have to buy all the other bits separately. Some of the other boxes actually need you to transport them in another lunch bag which is also very spendy and potentially another thing for my kids to lose :/
These boxes are easy to clean, I just pop them in the dishwasher.
I wondered whether the lunchboxes would be a bit heavy for my kids at 6 and 7 but they are completely happy, no complaints about the extra weight. I see these lunchboxes as having longevity as they are so big and configurable.
I'm really happy with our lunchboxes and the service is great too, the shipping was lightning fast and we got a personalised email message thanking us for our purchase. Thanks Bento Ninja fam.
