Review (4/5): and it is entirely comfortable to sleep with them in
Still experimenting with these. It can be a bit tricky to wrap the ends of hair around the roller to start and to bend the roller ends to hold the roller against the head. They are soft, and it is entirely comfortable to sleep with them in. A bit of product in damp hair helps to hold the curl afterward. This set offers enough rollers that you do not have to put much hair on each, so hair is dry all the way through when you take them out. I also use a spray bottle just to dampen hair or let the hair dry about 80% before putting the rollers in and leaving them overnight. They result in a lasting, bouncy curl.
