Just placed an order with Goulet for samples of Noodler's Black, Diamine Blue-Black, Iroshizuku Kon-peki and Shin-ryoku, 2 of the cleaning syringes he sells, and a J Herbin glass dip pen. Really excited for them to get here! I think what I'm most excited about are the Iro samples. I ordered the Kon-peki because it is just a unique shade of blue that stands out to me for some reason even through my notorious colorblindness and I grabbed some of the Shin-ryoku because green is my favorite color. I've seen Brian Goulet use the Kon-peki in various pens on videos before, but what about the Shin-ryoku? Does anyone have any experience with that one?
