Petrified Vertex Special Release
Premium Resin Special Release
Arizona is home to the Petrified Forest National Park a national monument spanning 346 square miles in northeastern Arizona. Known for it's dramatic fossils, especially the fallen, preserved trees that thrived in the region in the late Triassic Epoch, its an incredibly beautiful but often overlooked area in Arizona. "Petrified wood is a specific type of fossilized wood that is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement." - Source Wikipedia. While the Petrified Vertex is made from European resin, when we cut into this material it looked incredibly similar to many of the most dramatic pieces of petrified wood we've seen on our trips to the Petrified Forest National Park.
The Petrified Vertex Special Release is our snap-cap pocket fountain pen machined from premium European resin sourced from Turner's Workshop. The material is a custom acrylic material from Erinoid similar to currently available Venus or Toffee; featuring a base black acrylic with reddish-orange-copper swirl that has copper mica throughout the material. The material cut smooth and precise on our Swiss lathes, and during the sanding and polishing showed the true luster of the material. Hand-polishing during the final step shows a brilliant chatoyance throughout the copper swirls which is bolstered by the black depth of the base material. This is the best acrylic we've received from Erinoid, on par with Omas, Delta, and Conway Stewart materials we've featured in the past.
The bodies and caps are fully-machined in-house, and each piece is then taken through a multi-step wet-sanding and polishing process with a final soft-wheel technique that brings out the shine. Select from a variety of Makrolon, aluminum, or brass grip sections to customize your pen and a variety of polished steel nibs. Each pen ships with a Schmidt K5 converter and two black Monteverde ink cartridges in our recyclable packaging.

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.
