Well-behaving permanent blue or blue-black ink wanted

Hi Peter. I was thrilled to see your ink choice as I am a huge Platinum fan and have never used that ink so I do hope you tell us more after you have used it for a while. Joost at Appleboom did a wonderful interview with the Vice President of Platinum and I just ordered the Platinum President Pen as I wanted a bit bigger pen with that nice 18k gold nib and it came in the Chartres Blue which could be great with that blue pigmented ink. I might have to order that later.Well done Peter…and I hope you love your first house. I still remember mine in California with lovely memories. Regards,Barbara
