How long can you leave ink in a Rapidograph pen before you need to clean it?
Question: Justified curious how long you can leave ink in these pens before you risk having the ink start to gunk by the nature of the pen. If you keep the cap on the pen when not in use, how long can you leave ink in it?
Thank you.
Answer: I found that some inks are less sick than others, but a couple of days to a week was all that I "am" out of my inks. To be safe, clean, if you waited a week for the next use. You must have clean lines, after all.
