Pilot Hi-Tecpoint series is based on the unique ATT (Air Tight and Thought) system. A special mechanism in the cap ensures that the tip is sealed. This ensures that the pen, even after long periods of non-use, is available for writing and does not dry out. The ink supply is controlled in the pen by a so-called. Fine capillary system, which ensures that the ink through the temporary intermediate storage is gradually fed to the pen.
