I've been playing with semi-precious stones and shell. This is ebonite with strips of paua in an eccentric pattern around the barrel. The finial is paua as well. Thanks for looking.
That is very sharp. I like that a lot. I agree, I'd like to see a couple more pix of the pen including one closed. It's probably just me but the mirror is a little distracting on this pen. Again though, well done on the design.
