Cool [SEP] This is a cool set of wave rollers that come with a few needles which you can add links onto for the length of your hair. Sort of easy to put the silicone feeling rollers onto the needle, and you really have to try a few techniques to get it to work for the size, length and texture of your hair, and sometimes it's too tight, sometimes it's too loose, and sometimes you somehow miss hair, but it works pretty well to curl overnight. Not the easiest thing to sleep with, clearly, but curls come out bouncy and look great with all day wear. Great amount of set, perfect for thin hair like mine (I didn't use very many at all), and definitely for thick hair since there is such a huge set. Easy to clean, store, and a great addition for my heatless curls of the summer.
