on saleNoodler's 308 Refillable Cartridges (5-Pack)

I got a Noodler’s Ahab pen with its piston converter. The converter quickly gummed up and nothing I did fixed it. These refillable cartridges solved the issue. With the five pack you can quickly swap out different inks.

I got these to use in my Ahab pens and my Triple Tail. They work fantastic! They hold more ink than the pump fill units that the pens come with. They are easy to load up with ink. Though a little more fiddling to work with than the pump fillers. Just make sure your pens o-rings are in good shape, **** the cartridge on snug and make sure you have silicone grease on the threads where the cartridge screws on or your pen will drool and drip. Just visit your local hardware store and get pure silicone plumbers grease. A $4 - $6 tube of grease will last you for years if you use it sparingly as you should. The cartridge is the perfect addition to a well tuned Noodler's pen for a generous amount of ink. It will keep you writing or drawing for a long period of time. Even if your pen is set up to write very wet.

I have a couple of Ahabs, and just thought I would throw these in to the order to amortise the cost and wait. I suspect that they would make a usable alternative to the sample vials.

Work as described. These fit the Ahab/Neponsit/Tripple-Tail. If you remove the breather tube from the pen (don't lose it), the cartridge will even fit inside the pen body with the cap on (one way only....black cap towards the nib). With the cap on, the Ahab/Neponsit close all the way. The section on the Tripple-Tail has to be left a turn or two lose if you leave the cap on.When you remove the original converter, note that it was screwed down tightly and the threads were sealed with silicon grease. The cartridge also needs to be screwed on tightly and sealed with silicon grease. Otherwise, air may leak in through the threads.....and ink may drip out of the nib.

This is the way to ink your pen. Large amount of ink. Resealable cap stores on the loaded cartridge. Switch between inks at will. The Ahab and Niponset can both lay down a lot of ink. 308 feeds the need. Now my everyday writers.
