Same size as the "large" rollers--not "jumbo" [SEP] Do not buy these if you're looking for "jumbo" rollers. I previously bought the "large" size of these rollers and wanted bigger ones to make my curly hair straighter. These rollers are exactly the same size as the "large" rollers, even though they are advertised as being "jumbo." Very disappointed. Thank goodness Amazon makes returns easy. Back they go!
