Developed and commercialized by Pilot, the Capless is the world's first knock-type fountain pen, and has been a best-selling product for nearly half a century since its release in 1963.
Like a knock-type ballpoint pen, it allows for quick writing with just one knock, and when the nib is retracted, an airtight shutter mechanism prevents ink leakage and drying out.
Its original concept and superior functionality have earned it high praise both in Japan and overseas.
