New technology and high quality raw materials used to formulate this new pH-adjusted ink guarantees permanent and archival writing. Comfort of writing with a fountain pen was the main focus of this new product development.
Do make sure to replace the cap on your fountain pen after use to prevent blockages in the nib. Beyond this no special care is needed!
