Review on Calli Ink Set 1Oz Colors by Jessica Lewis

I have used this ink in my pen and feather calligraphy. It flows well without being too thin or thick. Color tests with blue and black did not fade in two years including 6 months on a spring/summer south facing window. I like that it washes out of the pen with water. Please note this is NOT permanent ink. One of the reasons why a little trouble removed it. I use a working fixer after I've finished my calligraphy and mask off any area I want to paint. I won't say never, but so far in my experience I haven't needed permanent ink. After all, the paper itself isn't waterproof, why should I? I recommend this product unreservedly.
