Converter for most standard Platinum fountain pens.
Screw-type piston fill.
NOTE: does NOT work with Platinum Preppy or Plaisir fountain pens if you drawn ink with converter attached. While the converter will fit perfectly well inside the pens, ink is only drawn into the feed, not into the converter. Can be used with these pens if you fill the converter outside the pen, then fit it pre-filled. Works normally with other Platinum pens.
