Chou Kuro is the blackest ink ever created from Platinum in its 104-year history! An ink that is blacker than black, and 46.8% darker than Platinum's famous Carbon Black, this new permanent ink from Platinum is going to set the new standard of what is possible from permanent black ink in the fountain pen market.
With the growing interest in fountain pen inks in recent years, the variation of ink colors is also increasing. In response to the customers request for a blacker ink, Platinum Pen has developed a new ink that is the best black ink ever in its long history of 104 years since its founding. The new ink, whose blackness has been proven by numerical values, offers an excellent visibility with a clear and intense black color, allowing you to keep memories and records on paper. In addition, it prevents the ink bleeding through onto paper while also being highly water-resistant and fade-resistant after writing, making the ink ideal for writing letters, journals and anything else you want to last a lifetime. Enjoy the true black color like never before.
Caution: Pigmented inks are intended for use in fountain pens, though they require more diligent maintenance and should not be left to dry out in a pen. It is best to clean it from your pen at least once a week to prevent clogging. Certain pens may handle pigmented inks better than others.
