The Platinum Preppy fountain pen is a lovely example of Japanese pen design. This new design features a smart, colored polycarbonate barrel that corresponds to the ink color. It's the same low-price, refillable fountain pen with an ink cartridge available in 7 colors. The cap is translucent, with a colored end cap and pocket clip to match the ink color. The hi-tech feed system ensures reliable ink flow. This pen features a fine nib that writes a 0.3mm line and uses Platinum Cartridge refills. It can also use standard international cartridges when fitted with the Platinum International Adaptor (available separately). Model PSQ-300 03.
