The Graf von Faber-Castell Pocket Pen has a half-turn mechanism to extract the tip. Its Platinum plated body measures only 9 cm in length, making it the ideal travel companion. Its cap with metal clip can be incorporated at the other end to lengthen the piece.
I found Iguana really friendly, helpful and efficient to both buy the pen and when I had a query - very quick to respond. The pen is gorgeous and I’m now using it every day.
