Charcoal grey marble looks stunning on the Aurora Optima fountain pen in mint condition. Fill it easily with a piston, and you'll never want to stop writing with it. Not a trace of wear can be found on this pen. Its 14k gold nib writes a very nice extra-fine line. No feedback with a light touch. Otherwise you might feel a normal amount of feedback for an extra-fine. A viewing window makes it easy to know if you have enough ink in the pen. Nice girth. Incredible Italian craftsmanship. 12.4cm capped.
