Ever wish there was a Parker Duofold Jr. Demonstrator? The Krone Everclear fountain pen is about as close as it gets! Like the Duofold, it is a button-filler. We just had this pen fully restored by Krone with a new ink sac. The pen has a little wear and some staining, but overall it is pretty good. Its two-tone 18k gold nib is marked "F" for fine, but it is closer to a medium for most people. It is also nice and smooth. Not the most common of pens, and we think you'll love it. 12.7cm capped.
