Couple of pen styles I haven't tried with kitless: closed end and flush cap/body. Nose cone bored out to fit Pilot G2 refills. Alumilite resin & 6061 aluminum.
The red one is "hot spot pink" by mutt blanks. I'm real pleased with how it polished once I hit it with the white diamond buffer. The other one is "Barista brown" but I can't remember who makes it. Both were bought from Exotics.
