I've used many brands of ink. From fusion, fantasia, intenze and beyond. For me, nothing compares to what I get from eternal ink. I had purchased a set at a convention in cali, the salesman was nice and even opted to have me give em a shot at least for the convention and if I hated them, he wasn't far for me to be able to tell him exactly what I thought.
Needless to say, I loved them. I bought a larger set. Most of the colors in my arsenal are in the 60 set.
You will not be disappointed.
