If you have three curling irons fighting for space under your sink, this kit replaces all of them. One styling base comes with three twist-on clip barrels (1", 1.25" and 1.5"), so you can go from defined curls to big, soft waves in seconds. The extra-long ceramic barrels fit more hair in each pass, for shiny curls with less frizz.

1. With the iron off and completely cool, hold it by the handle with the barrel pointing up. Turn the TightTwist lock to vertical and pull the barrel out.
2. Line up the pin on your new barrel with the side slot on the base, push it in, then twist the lock clockwise to horizontal to secure it.
3. Press the Power & Temperature button to turn it on. To change the heat, double-tap the button and keep pressing to scroll through the settings, then release and let the iron adjust.
4. Start with dry, detangled hair and a heat protectant. Clip the ends of a section, roll toward your scalp, hold until the heat has gone through, then release.
5. To turn it off, press and hold the Power & Temperature button until the lights cascade down.

Never swap barrels while the iron is hot, and keep the heated barrel away from your skin. It turns itself off after 1 hour. Don’t use it with a voltage converter, only a plug adapter.
