The best of its kind.. "I have used this brand and type of ink for over fifty years. I will be using it for the next fifty, at least. (I plan on a long life.) As a cartoonist and illustrator, it is not only the best ink for intensity, flow, and durability (no fading with time), it is the ONLY ink to use on bristol board and card stock.. Ever. It does not surprise me that it is the preferred ink for tattoo artists, too." — Alan W. (5/5)
