60ml bottle of Platinum Classic Forest Black iron gall fountain pen ink, 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.
From Platinum:
Fountain pen inks that are produced using traditional methods have many times been replaced with an ink that is made by mixing dye inks due to their time-consuming production techniques. Meanwhile, Platinum Pen is currently the only company in Japan that manufactures blue black ink in a classic way.
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.
