I've been coveting a PlanetBox for quite awhile now. It's pretty, it's stainless steel, you can decorate it with your choice of magnets, and it has a darling little matching bag to carry it in.
I was more than a bit excited when PlanetBox offered to send me a set to try out for the kids. They had some serious negotiations on the bag color (turquoise won) but managed to quickly compromise on the magnet set (there was a winter/skiing set).
In the end, Ben won, since Faith has another nice new set to use that was sent specifically for her, so it seemed only fair to at least let him use the other new box. He was really excited, and came home telling me that his teacher needed my blog address so I had to give him a card for her.
