Are there any "permanent" or close to permanent rollerball inks? I use both rollerball and fountain pens for journaling and note taking.  For journaling I use a fountain pen with Noodlers Bulletproof black ink because it is supposed to be at least somewhat permanent.  I can't seem to find any permanent or close to permanent ink refills for rollerball pens, do they exist? What are the &quot;permanent&quot; options for rollerball pens?
All Uni-ball rollerball inks seem to now be permanent (vs. water, UV, fading).  Pentel has permanent ink too.  Most manufacturers make this a clear selling point if you search 'permanent rollerball ink'.
