Pocket Fountain Pen

Clipless fountain pens aren't rare, but they can be controversial. The Vertex fountain pen wasn't our first try at a clipless fountain pen, in fact, it wasn't our second or third. But it's the only one that's stuck around and become a fan favorite. The design of the Vertex is based around the idea of a near-seamless transition from the grip to the body with an elongated grip made of acrylic or polycarbonate giving the impression of an "ink window". Secondarily, our implementation of o-rings in our pens allowed us to create a pen that caps with a custom o-ring, seals the nib with an o-ring, and seals the body with a third o-ring. Providing the possibility of eyedroppering the pen without the need for silicone grease. The shape is a modern cigar-style that draws inspiration from classic fountain pens from Wahl-Eversharp, Parker, and Sheaffer, but does so in a way that feels fresh and new. Though we designed the Vertex with resins and plastics in mind, we've since expanded to include aluminum, and most recently, fully-machined brass versions. Our most comfortable fountain pen by a large margin, the Vertex has quickly shot up the ranks in popularity, edging out the INK for our top fountain pen spot.

the photos don't do it justice. the color variation, the chatoyancy, the pattern in the resin, all are striking. the finish is impeccable. i don't know if Karas goes over the nibs but it is a great writer, too. i "super filled" it for it's first fill (with Karas' own desert varnish ink!) and it took 3.3 ml. that's a lot.

I have had a number of Karas pens but for some reason, this sticks out as my favorite. Normally I like colorful pens, but this is classy and really shows off the lines of the Vertex.

Exquisitely beautiful- unique- at the same time gliding on paper with the broad nib. Extremely sturdy and my favorite pen in the collection already. Great customer service

This is a real gem. The body and cap are very well made and the finish is excellent. It writes really well and is a moderately wet writer. I am so happy with my purchase nd the cost was very reasonable.
