This would be much cooler if they were mechanical pencils. Who uses pen when playing RPGs?
I do, but that's because I like to live dangerously ;)
If there was a set of mini-polyhedrals, I'd be all over it.
I'd buy it if it was DCC funky dice.
They have sold similar pens filled with D6 at Vegas tourist shops since I was a kid at least. No innovation here unless as others have mentioned they do a full set on Polyhedrals or something.
I see more & more gimmicky rpg kickstarters like this; what we want is quality content!
