This could be a reason all on its own to buy a Delrin Render K....

I had a crazy idea about the pen being translucent plastic; could double as a glow stick in a pinch? Not really, but the fact that it can "glow" is pretty cool.

From what they tell me, the guys at Karas Kustoms have just a few of these still laying around in the back that are available for purchase from their blog if anyone was interested.
