## Description

The scarce but popular Noodler's flex nib fountain pens enter a new design available in several new marbled colors. Each pen is uses a piston-filling mechanism which accepts bottled ink only (may we suggest Noodler's Ink?) and is fitted with a special auto-vent flex nib that can go from a hairline to 1.5mm stroke on paper using slight hand pressure to spread the tines of the nib. Definitely a great value considering the low cost to own a flex nib fountain pen.
