What was massdrop thinking when they add this ink in the essentials for writing section?!?
This is a great ink, but the shimmer properties makes it one of the most high maintanance inks to be found out there, because of the potential of clogging the feed.
I don't think it should be recommended to anyone who is not comfortable with disassembling a fountain pen for proper maintenance and who is willing to spend longer times in the cleaning process than with any other ink.
