I have the big plastic curlers (the kind where you need to use the clips) for when I want big curls, but I never use them because bonnet dryer broke a few years ago and I never bought another one. But I just found these really cool curlers. They don’t need clips because they have an elastic with a round ball on the end that keeps them in place. The curlers also have ridges which would keep the hair in place better. The curlers are from Kevin Murphy and these products are only sold at salons but lucky for us Amazon carries them. The curlers cost $36 (plus shipping).
