Remember when you were a kid and you'd bug your parents for bigger and bigger marker sets so you could get exactly the shades you wanted? It turns out that's not an issue for today's kids. As long as they can convince their parents to cough up $25 (although $40 at Amazon) for Crayola's miniature marker factory, they can engineer any shade that science allows.
The kit comes with everything a kid will need to design an entire box of markers actually, including three bottles of mixable ink, labels, and a couple of boxes. And not only does it let them finally find that exact shade of puke green they've been after, the kit also helps them develop important marker making skills. After all, a career's a career, right?
