Flex is Noodler's slim-sized flex fountain pen. It features a flexible steel nib, a handmade ebonite feed, and a built-in piston filling system with a blind cap at the end of the barrel.
Use light pressure on your down-strokes to spread the tines of the nib and create line variation. Don't write too quickly when flexing the pen, or else the ink flow won't be able to keep up and the pen will stop writing.
This pen is made of eco-friendly celluloid-derived vegetal resin. It has a distinctive smell that generally fades with time but never fully dissipates. Leaving the pen in direct sunlight can make the smell dissipate faster.
