Not so easy to find, but worth the search. A super-fineline gel roller pen for ultrasmooth writing with a newly formulated quick-drying ink. The 0.4mm needle point writes precise lines for when you need to cram a lot of information in a small space.
Select colors have even finer alternative point sizes: 0.25 and 0.30.
Dreamy with which to write on Clairefontaine paper or in your Moleskine or Rhodia. Also terrific for comics drawing where tight detail is desired.
If that's not enough, it's available in 16 vivid ink colors.
610m writing distance.
