This product could sell itself, it's a conductive ink pen, that is a circuit marker, how cool is that? Wait wait, it gets cooler! The team who created this ad will not only hypnotize you with the perfectly drawn lines that turn the lights on, but also they've cut the paper so they can pop up a little Lumino city-like city, right before your eyes. It's so magical I forgive the twee soundtrack. Also, I'll take an entire case of these pens, please.
