I got this to experiment with. I wanted to "drip" ink on my watery acrylic coated canvas and see what happens. I LIKE IT!!!! I also use this ink with a brush for calligraphy and for dark black colored details in my watercolor paintings.
A while back a good friend told me that if I like a particular ink brand and pad I should always order a coordinating reinker. It was a good idea then and is still that now.
