ADVANCED THERMAL TECHNOLOGY optimizes heat levels to help prevent damage. Ceramic rollers heat from within, while heated clips warm from the outside for long-lasting curls in just 5 minutes. For best results, use on dry or slightly damp hair only. FAST HEAT-UP: Roller rack heats in just 90 seconds, with a bright LED indicator. Important: End rings and clips may feel hotter due to dual heating. Always avoid touching the inner clips or metal rails during use. CUSTOMIZED CURLS: For soft, wavy curls, leave rollers in for just a couple of minutes; for tighter curls, 5–10 minutes works best. Rollers continue curling for about 15 minutes. Always ensure rollers are properly placed on the heating rails before use. 20-COUNT SET WITH EXCLUSIVE CLIPS: Includes 12 large (1-1/4") and 8 medium (1") rollers for a full head of curls. Exclusive clips provide a secure hold with reduced creasing. Unwind gently to avoid pulling hair when removing rollers. COMPACT & EFFICIENT: The vertical heating and storage base saves space on your dresser or countertop. Heats in just 1 minute 30 seconds for quick, easy styling. (120 volts, 60 Hz AC)
