The clear top does not “lock” into place, it does close though. The light does not come on when plugged in but they heat up as they should. Quick. Easy. Comfortable. Conair® Hot Sticks® is the innovative hairsetter that lets you explore a wide variety of curly styles with no clips needed. The kit comes complete with 14 flexible rollers designed with cool-touch rings and interlocking ends to secure and set your curls. Simply wrap your hair around the soft rollers and lock them into place to get the curly looks you love. The rollers heat up quickly, so there's less waiting and more styling. Use the small-size rollers to create cascades of ringlets, or go with the medium-size rollers for beautiful spiral curls. The rollers are designed with tourmaline ceramic to generate even heat and leave hair with less frizz and damage and more shine and manageability. The result: Healthy-looking, frizz-free curls that any salon stylist would envy.
