Introduced in late 2011, and named after Captain Ahab of Moby Dick fame, Noodler's Ahab Flex fountain pen line is proudly manufactured using biodegradable materials from a renewable resource. Lapis Inferno has a blue and white swirl body with silver accents, and a piston filling mechanism. This pen can be adapted to be an eyedropper filler by removing the piston. If you've never written with a flex nib, you may find it takes some practice; but the results will be worth your effort! Varying your writing pressure can widen and narrow your script, creating your own unique style.
