The Platinum Preppy fountain pen is the perfect entry-level fountain pen with a great reputation for its quality and design! 0.3mm nib is perfect for fine notes and corrections. The ink flows smoothly. The clear grip design allows you to see the ink flow and amount of ink left in the cartridge. Platinum's patented "Slip and Seal" cap design prevents the ink from drying up for a year. The pen comes with one cartridge. Replacement Platinum ink cartridges are available in a range of colors. The Preppy also accepts a Platium converter to fill with bottle ink or can be converted to an eyedropper.
