I HAVE USED THESE FOR YEARS AND THEM THE STORE I PURCHASED THEM FROM STOPPED CARRING THEM.  WHEN I SAW THEM ON AMAZON I WAS DELIGHTED.  MY DAUGHTER ALSO USES THEM SO I ORDERED 5 SETS AND SENT HER 2 AND KEPT 3 FOR MYSELF.  LOVE THEM AND IT'S SO EASY BECAUSE I DON'T TAKE THEM OUT ONCE THEY ARE IN.  YOU JUST WASH AS USUAL AND THEY ARE THERE WHEN YOU PUT THE ITEM BACK ON.
