The G-307 gel ink cartridge...
, December 12, 2011
The G-307 gel ink cartridge is the way to go! Very smooth and never skips like
the C-307 cartridges have a tendency to do. Might be the perfect ink cartridge,
and I've been searching for that for a long time. The G-307 is smooth in a
controlled way for a .7mm cartridge, and doesn't get sloppy the way the Parker
Gel Ink refills can get. Only issue might be how long they last and whether or
not they begin to write differently towards the end of their capacity. Will keep
you posted. Makes my Orcas the perfect pens!
