They have been on the market here for several years. They started out looking like wash cloths, but lasted forever. I had one for each of the 3 machines here at the blg. They lasted me about a year. About 2 yrs. later they went to the paper ones. You can use them 3-4 times (at least I do). I can find them any time at the local store or at the WalMarts. They are good.
