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.
my black pad was getting dry and i was glad to finally find a reinker so i wouldn't be forced to buy another pad.
Though Memento pads last so long I use them exclusively, glad there is a refill now,
