Review title is Easier if your hair is shorter than 22", but still useful for longer hair [SEP] These curlers extend out to around 20" so hair that is any longer than about 22" will end up having a strange gap between where your roots are and the curl begins, depending on how you place them.  I usually line them up so I have that strange gap, but use it to my advantage and just work things into an updo of some kind.<br />The curlers are flexible and comfortable enough to sleep in, just pop a bonnet on and you're good to go. The ends are topped with a silicone gasket-type end that grips onto your hair, preventing it from slipping once in place.<br />The hair grabber tool is basically a big crochet hook for your hair and has two parts you assemble by snapping them together. It is best to work in small sections, especially if you have thicker/dense hair so you can really maximize the curl these provide.<br />There are 20 in a bag, I'm not sure there's really much difference between the two colors in the bag. The curl this gives is really nice and gives great body after a day of wear.<br />Overall, these are a fun addition and a way to take some time off your hair routine in the morning.
