Sold out at the moment, but if you like this, send an email to Pierre@DesiderataPens.com, and I’ll let you know when I have them again.
Eucalyptus Burl wood. It’s expensive, a headache to deal with, and time consuming to finish, but the results are stellar.
Your pen probably won’t be the one in the picture, so there will be variations between the pens, as wood never does the same thing twice.
These pens (may) have wooden threads. They look amazing, but they may be a bit tight occasionally, so you may want to oil them from time to time.
Though designed for the Zebra G nib, you can use any threaded #6 JoWo nib unit in here, and it will just screw in.
You can also get a Pilot XF for it too. If you do, you’ll get a special nib unit that I make which adapts the Pilot nib and feed to the JoWo #6 internal dimensions that my pens have. They’re a hassle to make, but they’re great units.
