Quink

Quink (a portmanteau word from 'quick' and 'ink', or "Quisumbing Ink") is an ink developed by The Parker Pen Company and Francisco Quisumbing, a Filipino chemist. The ink became a new writing system, drying by absorption rather than evaporation, when used with the Parker 51 pen, which was introduced ten years after Quink's release into the marketplace.
