Noodler's added the Konrad Flex fountain pen collection in late 2012. Though somewhat smaller than the Ahab collection, this line is also proudly manufactured using biodegradable materials from a renewable resource. Northern Pike has a red swirl cap and red demonstrator body, making the piston mechanism visible. 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.
