Great Product [SEP] I love all the different sizes. I am 1- year newly natural and purchased this set for when my hair continue to grow and I get length. The purple and gray rods are the largest so they don't bend as easily or more flexible as the smaller rod do--but they DO bend. Worth the money cost me $21 (I waited until the price went down again from $35) because if bought the packages individually it would have been expensive.
