This is a very quirky lunch bag indeed! I love it, I do.. it's much more roomy than you might think initially. I can fit a sandwich box, a piece of cake, cookies, and an orange with no problem. No drinks, though, because that might make it too heavy.
The only real problem I have with this paper bag is that it doesn't have a handle. Which is why I gave it only three stars, as it is a real problem when you are carrying a lot of things and it starts to feel heavy. ALso, it could do with being a little bit taller, as it gets very short once you fold it so that the magnets engage. And I know that other reviewers considered this to be quite flimsy, but let me tell you it withstood a bit of rain and a lot of suffering, as I am not the most careful person in the world. It holds up just fine!
All in all it was an ok purchase, even though I have to say I might not buy it a second time. Also, it is more of a "guy accessory" and being a woman who likes a bit of colour I've already ordered a pink lunch bag!
