This is a Hi-Tec-C pen made by Pilot Corporation (PILOT). These pens are partially used and mostly clogged with ink, making them unusable. Therefore, I would like to offer them to someone with the expertise and ability to repair and reuse them. I am currently decluttering, so your cooperation would be greatly appreciated.
