【15-Second Rapid Preheat】The eyelash curler has a temperature sensor that lets you know at a glance when it's ready to use. After about 15 seconds, the indicator light changes from red to white, making it easy to see the preheating status and indicating it's ready for use. 【3-Level Temperature Adjustment】To meet the diverse needs of our customers, we've scientifically designed a 3-level temperature adjustment (65/75/85℃). You can adjust the temperature to suit your eyelashes. 【10-Minute Auto Shut-Off】A high-performance IC chip automatically controls the optimal temperature, and the power automatically turns off after 10 minutes of inactivity, so you don't have to worry even if you forget to turn it off, ensuring safety. 【Anti-Scald Design】The concave-convex design is used, and the heating wire does not come into contact with the skin at a precise distance of 0.3CM, so there is no need to worry about burns on the eyelids. It creates a natural look with beautiful curls that won't damage your skin or eyelashes. 【USB Rechargeable】It uses a large-capacity lithium battery and has a compact design for easy portability. It's rechargeable, eliminating the hassle of battery replacement. Suitable for all places such as business trips, travel, camping, dates, offices, and homes.
