Xezo Brass Fine Rollerball Pen in French Blue Metallic Color, Diamond-Cut Engraved, Platinum Plated, Serialized (Incognito Blue R)
The Incognito series of rollerball pens was created with the goal to produce a quality, weight-balanced luxury pen with a comfortable grip. The weight distribution of the pen’s body was designed to allow for the friction to be minimized at the tip of the pen. This series is produced in limited edition and each pen is numbered by engraving (production ended in 2016 with total of about 600 pieces made). Each pen is produced with.999 platinum-plated fittings, and the body is made of solid brass with diamond cut engraving. The roller pen features a screw-on cap and German or Swiss-made fine width rollerball refill
