I typically avoid brown tone ink due to conflicts from work but this color… Sorry, I underestimated it. This color is saturated with beautiful shading. While writing, you have fun with the color changing (also estimate how fast you write) which similar to KWZ IG Red #3.
The down side is, it is not waterproof. Oh well, look from the bright side. It doesn’t bleed through iPaper UCCU, no feathering on DoubleA, and just left a little bit of trace on ChaShin paper. It’s a good ink for daily use.
CP value: 92/100, as I was surprised!
