This right here boys, is the best one I've found so far. They work great for plastisol and even better for waterbase inks. They are so cheap, I buy them by the dozen.
prefer these for waterbase and even then can swirl the ink right outa the cup and all over you. to many nooks and crannies to clean for plastisol for my liking and the plastic gets softened by some ink cleaners.
plastisol doesn't want to be whipped up like WB does, if you stir it to fast, it heats up. Look at the turnabout from M&R.. it's a slow folding of the ink.
