The metal portions of this pen are Rhodium and 24k Gold plate.   You can have it made with the same distillery wood as your ring!  

It is available two finishes (wax/oil finish pictured):

Wax + Oil:  Beeswax, Caranuba, and Mineral Oil blend provides basic protection for the wood. 

• Basic protection from water/staining/dirt from hands.  Will wear off with heavy use
• EASY to restore - wipe on butcher block conditioner, wait a few minutes, wipe off
• Wonderful, natural wood feel

Cyanoacrylate (aka superglue): The go-to for small woodturning

• Comprehensive protection from water/staining/hand oils.  Possible to wear it out, but relatively tough
• Feels like plastic (it is)
• Impossible to restore once the pen is assembled.

Medium, German-made Iridium tip

Includes one disposable fill and once refillable cartridge.
