For curls and waves, this set of hot rollers comes with 20 rollers—8 extra-large (1¼ inch), 6 large (1 inch), and 6 medium (¾ inch)—that create smooth, healthy-looking results that last. The ceramic-flocked rollers heat up in 85 seconds with even heat for consistent curling from start to finish. 20 heated clips stay warm on a heated rail and secure hair around the roller whenever you need extra heat to lock in a curl. Curls in Minutes: Create tight curls with small rollers in about 10 minutes and soft, wavy curls with larger rollers in even less time Keep in the Heat: Case cover maintains roller heat at the optimum temperature. This is essentially brand new. I used only once and was too lazy to continue using them.
