Created from the lava rock of Europe's most dangerous volcano, this Spartacus fountain pen is as unique as the material taken from Italy's famed Mount Vesuvius. Formed from pulverized lava rock and resin, the material is reconstituted into a workable material to create this unique pen. Natural in colour, it has hygroscopic properties, making for an easier grip on the pen for an improved writing experience. The #6 medium nib is German-made and iridium tipped, created for longevity and smooth writing. Spartacus features antique pewter fittings with a sword for a clip, columns and a Classical Roman column for the finial. This material is unique to Just Write Ink. This is truly a unique pen that would make a truly memorable gift.
