Where To Buy (No Affiliate Links)
Shading: The saturated nature of this ink kept shading to a minimum.
Bleed Through: Copy paper experiences bleeding as well as feathering. As usual, Rhodia fairs quite well. Field Notes performs better than I expected with only the most minor of spot bleeding.
Show Through: The backside of Copy paper is not suitable for use. The backside of Rhodia is just fine for use however, and Field Notes is pretty good too.
Saturation: Highly saturated.
Water Resistance: This ink has no water resistance.
Drying Time: Very long, 40+ seconds using an EF nib on Rhodia.
Flow: Average flow. Average lubrication.
Cleaning: Yet to be determined. Will update.
Colour Make Up

If you are looking for a unique but still conservative ink for use in the workplace, this is one you should sample. Be warned though, it performs well on good quality paper but stumbles on the cheap copy paper that you will likely find in your office. For myself, I think that I will give this one a pass.
Other Reviews For This Ink
I reached out to Diamine and asked if they would be willing to supply samples of the complete line of the 150th Anniversary inks. I do not feel that my opinions of this ink have been affected by receiving the sample free of charge.
