The Remington Ionic Conditioning Hair Setter uses exclusive thermal wax core rollers to create long lasting curls. The wax core allows the roller to retain high heat longer and create long lasting curls and volume*. The 20 velvety rollers feature Ionic Conditioning so your curls have less frizz and more shine*. Three color-coded clip and roller sizes (¾”, 1”, 1¼”) allow you to customize your look and cover your whole head! The exclusive J-clips are specially designed to securely hold the roller in your hair with less creasing*. The ready indicator light lets your know when the rollers are the perfect temperature for styling, and the cool touch ends make these rollers comfortable to use. Plus, the two-year limited warranty adds peace of mind.
