Spalted signature wood with ebonite ends, mosaic pin in each end, and gilding and patination. 12X.8 triple tap and die for the cap and body connection. What a difference a triple makes. Only 2 1/2 turns to close where my other pens took 6-8 turns or twists. All other threads are singles. Its about 5 1/2 inches closed with a #5 Jowo nib. State any type of comment you want. Thanks for looking.
