The Perfect Pen

The Perfect Pen would be one of modular design. It would have a plastic body that could be customized with different cushioned/non-cushioned grips in different colors. An executive line could also be made, possibly of metal or resin and come in darker colors with silver or gold trim. It would have an replaceable ink cartridge of liquid ink which would be made in as large a capacity as possible within the design limits. It would have replaceable nibs. The nibs would be available in needle and conical points and in felt tip points. As well it could incorporate fountain pen nibs and calligraphy nibs. They would be available in a wide range of sizes and be replaceable while there is still ink in the pen. They would be semi-permanent: washable/reusable (with storage tubes to keep them in) but inexpensive enough to be disposable if clogged/damaged/worn out. This way the ink supply could be sold in lots of a dozen and in as many colors as possible. The nibs could be sold individually and in sets. The cap would be the screw on type, or a tight press on fit, with a rubber o-ring as a seal so the pens could be stored short-term without worry. For long term storage, take the pen apart, clean it and store it (the ink cartridge would have a cap for just such a purpose). Now, if we could just get a major pen manufacturer to make it a viable pen.
