Platinum
Black, Blue-Black, Red
In 1919 Syunichi Nakata started a pen company, later renamed Platinum Pen Company.
Platinum inks are available in bottles or cartridges and in three colours. The black has a rich dark tone. I have not come across the ink recently in my travels through various stores. It was a number of years ago that I tried out the black.
May 2008 - I checked and this ink was available online through www.cajunpen.com
