  • Here is 2024 stock on the Model 20 in what Franklin-Christoph calls their Bluestone acrylic material. This is a friction fit, slip cap pen with a recessed nib.
  • Precision machining and design create a cap that securely and firmly fits to the section and barrel with a firm grip. When capped or posted properly it is impossible to sling the cap off, so can be securely used in a shirt pocket or pen pouch.
  • No exterior threads and no shoulder from grip section to barrel.
  • The pressure is distributed inside the cap and away from the lip to prevent lip cracking.
  • The interior of the cap has a feature that releases air pressure to eliminate the vacuum that causes ink spurts on the nib when uncapping.
  • Filled 3 ways, via disposable cartridge, piston converter, or the eye dropper method. Barrel holds approximately 3.5ml of ink when eyedroppered.
  • Comes with a choice of #6 HP Steel Franklin-Christoph factory nib choices, a converter, two ink cartridges, a single pen pouch, and a white gift box. 
  • Best for the advanced fountain pen user.
  • Lifetime warranty and Made in the USA
