People, I really like this pen project! As a lover of plant dyes, I think it's so cool
that this pen writes with wine, soy sauce spinach juice, food coloring, etc.
All the dyes you can come up with. You can make you own colors, try out new
stuff, have fun. I backed their Kickstarter campaign a whole while ago, and I
have been waiting for the pen to be sent to me for too long. But it looks like that
wait will be over soon.
Check out this movie they just sent out.
