these at least curl my hair for the short term [SEP] because this kind of curler is only available on amazon i am stuck with these imports but they do curl my hair until they fall apart after several weeks the good news is that i have saved my old usa made plastic curler frames so i toss the flimsy plastic frames that come with these amazon rollers and i then put the new foam cylinders onto the old sturdy frames that i have kept this process is my only option goody no longer makes these curlers in the usa so the ones purchased from amazon are still better than nothing at all kp harwell
