Gravitas Pocket Fountain Pen Pultruded Carbon Fiber Eyedropper

The Gravitas Pocket Pultruded Carbon Fiber Eyedropper is a compact, ultra-durable fountain pen designed for maximum portability and writing performance.

Crafted from pultruded carbon fibre, this technical material is processed using a proprietary technique for strength and lightness. The raw tubes are formed through a heated die process and then precision-machined.

This model features a dedicated eyedropper filling system only, with a double Delrin liner that holds up to 1 ml of ink. It is not compatible with cartridges or converters.

Triple-start threads allow quick uncapping with just 1.5 turns, and a flat facet along the barrel serves as a practical roll-stop. When posted, the Pocket pen extends to full-length size for comfortable long writing sessions.

The black PVD-coated grip section, tapering from 11.85 mm to 9.8 mm, features micro-machined grooves for a secure grip. The pen is fitted with a black steel size 6 nib made by Gravitas and a striking red ebonite feeder. Red accents—including the logo on the cap and the O-ring—add contrast to the satin-finished black carbon body.

Comes with a 1 ml eyedropper for filling. Do not exceed 1 ml of ink for best performance.
