Platinum Chou Kuro pigment ink black
The blackest ink in Platinum's Pen history in over 100 years.
With the growing interest in fountain pen inks in recent years, the variation of ink colors is also increasing. In response to customers requests to a blacker ink, Platinum has developped a new ink which is the blackest ever in it's long history of 104 years since it's fouding. 
The new ink, which blackness has been proven by numerical values, offers an excellent visibility and intense black color, allowing you to keep memories and records on paper.
In addition, it prevents the ink from bleeding through on the paper, while also being highly water resistant and fade resistant after writing, making the ink ideal for letters, journals and everything you would want to last for a lifetime. 
When cleaning the pen nib after using Chou Kuro ink, use purified water. Avoid washing it with tap water as it may react with minerals contained in the water and makes it difficult to remove the stains.
