monocPilot Acroball T series, Retractable Ballpoint Pen, 0.5mm Black Ink, 5 Body Colors set Sticky Note(Japan Import)

It’s very light the ink, to what im typically used to but writes very well, precise. My hand gets tired quicker though. Would certainly buy these again. I gifted them as well. I love the different colors it comes in. The exterior not the ink itself.
