Noodler's Ahab Flex Fountain Pen - Truk Lagoon
The Noodler's Ahab flex pen features a steel flexible #6 nib and a slide piston mechanism. If you'd like, you can even remove the piston mechanism and use the pen as an eyedropper for a massive 6ml ink capacity. This translucent turquoise demonstrator Ahab is made of a celluloid derivative and is technically biodegradable and formed from a "renewable resource". 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 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!
Due to the residual machining oils used when cutting the feeds for these pens, we highly encourage you to give the pen a good flush before use. We recommend any of the following options: distilled water, water with a touch of dish soap, a pre-packaged pen flush, or a solution of 10% clear ammonia to water. This should resolve most ink flow issues!

Customer Reviews
This pen worked really well right away and was really easy to fill! It was great for the price! My only problem is that the pen itself has a horrible chemical smell to it right out of the box, however over three days of leaving it sat out after cleaning, the smell is much fainter, though still not gone.
I saw mixed reviews and that made me hesitant to buy but I'm so so glad I did! It wrights beautifully, I love how shimmers look. It puts down a good amount of ink but definitely not as wet as the triple flex. If you are wondering to get it or not just do it!!

I like the pen for doodling. The flex nib is a lot of fun. I purchased some empty cartridges to fill, gets way more capacity without having to do the eye dropper deal. I need to get another one of these pens to put a FPR flex nib in, since I like the stock noodlers nib, but need some more variation.
I have a trick to get rid of the smell: wash in warm soapy water, dry, then place in an airtight container covered with Downy Unstoppables laundry scent granules for 3 days. I used "Fresh" scent. Miraculous!
