This pen has an unusually great feel - there's something unique about the rubber
and dimensions that works unlike the rest, it's in the Top-Class of
Blue/Black's. Not scratchy, great color and intensity.
Super-slim. Excellent cartridge, not an everyday pen for me, but it has its
uses. Unique in form and application, a little rattling going on with the
cartridge but no big deal. Good fine-tuning detailed work.
