You. Thank u!
Sheaffer Skrip ink is a water-based pigment ink. It is not advisable to use an acrylic ink in a fountain pen as this can dry in the feeder creating a blockage which stops the ink flow. Once acrylic ink has dried in a feeder it is almost impossible to remove and may render the pen useless.
