From Jeff:
"As for the pen, it is a Black Titanium Cigar pen as you can tell. The ink cartridge has been upgraded from the standard Parker insert to a Private Reserve Ink from exoticblanks.com. You should find that it writes incredibly smooth - pressing the quality of a rollerball.
The pen barrels are not hand cast by me. They are in fact, antique bakelite. I found the bakelite rod (curtain rod I believe) in a deep yellow with a little swirl visible. Turning off the outer patina, the rod itself was white swirl. The tubes and inside of the blanks were painted in red and blue using a semi-opaque enamel paint. I kept the colours in the semi-opaque state to allow the shine and shimmer of the brass tubes to help accent the final colours. The fact that the colours are actually on the inside of the blank allows for the depth and variation within the colours of the barrel that you see."
