REALLY cool design, and neat looking pen. There's an article in one of the polymer clay magazines from late last year or early this year about a guy who has specially-made slimline kits for use with polymer clay. If I recall correctly, his components do not press fit; they are simply glued into place. This is to help prevent introducing any stress onto the PC during assembly. Others here have spoken about using PC for pen bodies, and I think they mentioned that it is fairly brittle. I thought about trying CA to help "stabilize" the PC, and will be curious to hear how this pen holds up. Please keep us updated!
