Review title is Great twisty curlers. [SEP] These work great to give small, tight curls. You can sleep in them, although it's a little uncomfortable, so takes some getting used to sleeping on lumps. I sometimes double them up and put two together, to get larger, looser curls. I love how they're easy to twist the ends to hold them perfectly in place. I'd like to get some in a larger size, for bigger curls too.
