When using this ink, we recommend giving your pen a good cleaning every 4 to 6 weeks, or if you don't plan on using the pen for a week or longer.Please note: Pigmented inks are suitable for use in fountain pens, however, they require a little more care and attention and should not be left to dry out in a pen. For best results, use it with an absorbent paper and allow it to dry for 24 hours before exposing the ink to water. It is a good idea to clean your pen every week to prevent the ink drying and clogging the nib and feed. This ink contains pigment particles, which can cause clogging if allowed to dry out inside of a pen.
