If you love great pens, flexi nibs and functional artwork, then the Franklin-Christoph Panther 40 Diamondtree fountain pen is for you! This truly limited edition pen is only #31 of 51. Franklin-Christoph took its Panther 40 model pen and had Maki-e artist Katsunobu Nishihara use platinum dust, mother-of-pearl and six layers of urushi to create a masterpiece. Better yet, it comes with a Franklin-Christoph 14k gold flexi nib! Unfortunately, we don't have the original box, but this pen is still pretty remarkable. Aside from a few traces of wear, there are no cracks or deep scratches. Click the photo for close-ups, but the mother-of-pearl "diamonds" in the tree really pop much better in real life. Smooth, easy flexing from extra-fine to maybe around .75mm wide. Comes with original converter. 13.8cm capped.
