I got an answer from a consultant who called up the office to confirm for sure their thoughts... This is what they said: "We wouldn’t advise you to use the current re-inkers on the older style ink pads, even if they are the same color. We have a different formula for the inks that we now use, and they won’t work correctly with the ink that was in the previous ink pads."
So, now on to trying new brands... who knows I might end up w/ CTMH again
