I bought a Kuretake way back when I hadda order it from Japan. It was the "sumi" model, but it still hadda nylon brush nib. I use Platinum Carbon Black ink, a Platinum converter, and never clean it. I was advised to buy an extra tip and toss the pen's cap for the plastic cap that comes with the extra tip, which I did.
So, I have a 2nd tip on the original pen and and a brand new one I jes found.
