The Platinum Preppy fountain pen is a lovely example of Japanese pen design with a smart coloured polycarbonate barrel corresponding to the colour of the ink. It's a low-price refillable fountain pen with an ink cartridge in one of 3 colours. The cap is translucent, with a coloured end cap and pocket clip to match the ink colour. This pen features a hi-tech feed system for reliable ink flow and a medium nib that writes a 0.5mm line. It uses Platinum Cartridge refills and can also use standard international cartridges when fitted with the Platinum International Adaptor (available separately). Model PSQ-300 05.
