I don't use this pen...
April 25, 2012
I don't use this pen every day but have had it for quite a while. I decided when then original cartridge was finished, I would buy the carbon ink. I still am using the original cartridge. The line is so thin that the cartridge lasts a long time. Some day I will get to buy the ink bottle. Anyway, my point is that even though the cartridges may seem expensive, they last a long time.
