I have several colors of "pigment ink" that I bought from Hobby Lobby. I didn't know what the difference was between that and the other ink they had. I noticed that when I stamped on a picture it pretty much wipes right off.
Do you stamp on pictures? If so what kind of ink do you use? Do you know what the other ink is in the same little pads and is used for something different than pigment ink? What is pigment ink used for?
