Noodler's Ink Flex Nib Creaper fountain pens have a modern design with traditional components. They come with a piston filling mechanism that accepts any fountain pen ink, even those with a high-viscosity. The stainless steel nib has the right amount of "flex" - with slight pressure you can spread the tines and increase the ink flow, achieving an optimal line width. The resin barrel of the pen has a slender frame with a small window to see how much ink you have left.
Comes in a box with detailed instructions on use.
