Noodler’s Ahab Flex Pens are a novelty, there’s no question about that. But one of the best things about the pen is that the whole thing is easy to take apart and maintain. The design of this pen is genius in its simplicity. And Nathan (the pen’s designer) has already improved upon his already good design.

The original o-ring that is shipping on the first batch of Ahab Flex pens is a standard o-ring, that is there specifically because it’s replaceable with o-rings you can get at any home center. Nathan designed a new double-wall o-ring for the Ahab pen, so that a bead of silicone grease can fit between the two walls.

We’re told that future batches of the Ahab pens will be coming standard with the double-wall o-rings, but for the first batch of pens, they will include the regular round ones. If you want to upgrade to the new ones, you’ll need to drop just an extra $1 for a pair of them. It’s not something you have to do to have a well-functioning pen, but the option is there for you if you so choose.
