The Platinum Classic Khaki Black iron gall fountain pen ink comes with a built-in reservoir for easy filling. The color will darken on the page within the first 24 hours after writing, even as soon as one hour later you may see a difference.
The ink color that is bright when you start writing becomes gradually black. It is also highly water resistant and suitable for permanent preservation. This time, we have paid close attention to the process of changes in color of the classic ink, and have released six new colors with the aim to enhance the joy of using fountain pens. Emphasis on the shading has been placed, offering a rich deep writing. Please try our CLASSIC INK that will further expand the ability to enjoy writing with the fountain pens.
