【Safe and Secure Design & Ergonomic Comb Design】: The ergonomically designed arc comb fits perfectly to the eyeliner, firmly catching both upper and lower lashes. This hot eyelash curler utilizes the latest technology and has been developed to match the curve of Japanese women's eyelids. The heater part is designed to maintain an appropriate distance from the eyelids, preventing damage to the skin and contact with high temperatures, while the body's uneven design completely prevents burns. It's a design that balances safety and ease of use. In the unlikely event you forget to turn it off, it has an automatic shut-off function after 5 minutes, so you can use it with peace of mind. You can create beautiful eyelashes safely and quickly. 【3-Level Temperature Adjustment for a Gentle Approach to Eyelashes】: This hot eyelash curler has 3-level temperature adjustment from 45°C to 85°C, allowing you to choose the perfect temperature for your eyelash type (soft 45°C, normal 65°C, hard 85°C) and style. The set temperature can be easily checked on the bright LED display. You can finely adjust the temperature to match your eyelashes, achieving ideal curling. 【Lightweight & Compact & USB Charging】: This advanced heated eyelash curler is conveniently USB rechargeable. It is equipped with a large-capacity 300mAh lithium battery and can be used for up to 25 days with approximately 1 hour of charging. Weighing only 32g, it's lightweight and easy to carry anywhere, such as on business trips, travels, camping, dates, or to the office. You can achieve attractive eyelash makeup anytime, anywhere! 【Safe Design with Silicone Material & Washable】: This is an improved version of the conventional hot eyelash curler with exposed heating elements. Safety is improved by protecting the tip with silicone, eliminating the worry of burns. After turning on the power and setting your desired temperature, the tip of the 3D curling brush will react to the heat after about 10 seconds. The tip is covered with silicone, so it is washable. You can easily clean it at any time and maintain a clean condition.
