I use Versamagic, versafine and memento inks.
Recently, I bought Vivid inks
because I had read on the Stamp TV website that they are very good for solid images. I placed my first order just to try them, then I placed a second order and I have almost all the colors
They are very very good but they cannot be used with Copic Marker.
I used them on different types or cardstock, included a textured envelope and the impression is great.
