Noodler's Topkapi Amber Standard Flex Fountain Pen
This translucent orange demonstrator Noodler's Nib Creaper flex fountain pen features a small, slender body with a steel flexible #2 nib and a twist piston mechanism. A small ink window shows how much ink is left in your pen. These pens are made from a celluloid derivative. The vegetal resin body of this pen may show particles or striations within the material. This is most noticeable in demonstrators and bright colors.
The Nib Creaper (also known as the "Standard Flex Pen") was the first fountain pen produced by Noodler's, introduced in 2010. The Noodler's flex pens were designed for the hands-on tinkerer - they are made to be taken apart and adjusted. The nib and feed pull right out and can be adjusted and heat set for optimal performance. Don't be afraid to get a little ink on your fingers while you learn how to use this pen.
As a simple rule of thumb for writing with a flex pen, just apply slight pressure on your downstrokes, which will spread the tines and increase the line width, achieving that optimal line variation. Make sure to go slowly so that the ink can keep up with your writing. As with any flex pen, it just takes practice!
