Sailor’s entry into the dip pen market. The Fine and 1mm versions have an optional feed that can be attached (sold separately) while the 2mm and the “Brushstroke” or Fude versions have this feed installed already.
Initial tests with the 2mm show excellent results, with much writing or swatching possible on a single dip, cleanup is also quick and easy, with the only possible drawback being a bit of time to dry between different inks.
