Franklin-Christoph Model 20 Fountain Pen - Scottish Heather NOS

Franklin-Christoph Model 20 in beautiful Scottish Heather 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.
