The Vertex is the second release in our Signature Series which is built around using plastics and other resins as the main parts of the pen. From the beginning, we wanted to create something that looked, felt and functioned differently than other pens on the market. We wanted a smooth transition from grip to barrel, so we moved the traditional breakpoint from the section back, and used a third o-ring in the cap adapted slip cap functionality for the pen. The longer grip section allows for the use of an "ink window" with transparent materials which adds a little flair to the pen. The Vertex looks and feels streamlined and aerodynamic. With soft tapers, a cigar-shaped body, and a concave cap top; the Vertex is at once futuristic but also reminiscent of the classic lines of Parker and Sheaffer pens. After a few years of perfecting the Vertex, we're now expanding into non-resin materials with the launch of the production aluminum Vertex options starting with the Tumbled Aluminum Vertex.

The Tumbled Vertex fountain pen features the style that sets this pen apart while retaining MOST of the functions of the original pen. The overall size is nearly the same with the cap outer diameter being slightly smaller than the original resin versions. This pen utilizes the same grip sections and o-rings making the Vertex now standardized in both resin and metal. The only feature lacking in the Tumbled Vertex fountain pen is the ability to eyedropper this pen. While it technically CAN be done, we don't suggest it due to the fact that the ink WILL stain the aluminum and certain inks can cause corrosion and pitting due to the pH level of the ink. However, feel free to use the supplied Schmidt K5 converter with your favorite ink or a massive list of standard international cartridges. The caps and bodies of this pen have been put through our time-tested tumbling process to give it that slightly worn look that is perfect for everyday carry. Choose from all of our available grip section offerings in durable Makrolon, anodized aluminum, or upgrade to polished brass. Select from a wide variety of nibs in polished steel to further customize your pen to your specifications. Ships in our recyclable packaging with a custom vinyl sticker. The Vertex fountain pen is the latest step in our Design.History.Technology influenced Signature Series. Comes standard with a Bock polished steel nib which are manufactured by Peter Bock in Germany. Also included with each pen are 2 black Monteverde ink cartridges. Each pen is designed and machined, by us, in the USA.
