No its actually a cap--- You roll your hair (dry) and put the cap in the microwave for about a minute or two. Then you put the cap on your hair and wait about two minutes -- take the rollers out and it should be curly.
Hi i just have a question this is just for the cap right? Cause I went to check it out on youtube and I saw how it works but I just wanna know if it came with rollers r with out k thanks
