Perfect for daily sleep, breaks during desk work or study, and naps. 【4-level temperature adjustment function】Easy operation with one button. Adjustable in 4 levels: 45°C, 50°C, 55°C, and 60°C. Using graphene material with excellent thermal conductivity and heat retention, you can feel a pleasant warmth in about 3 seconds after turning on the power. Enjoy the ultimate relaxation time. 【100% light blocking】The design fits the nasal wings, completely blocking out light. Other eye masks on the market do not have a nasal wing fit design, and light enters through the gaps around the nose, so complete light blocking cannot be achieved. 【Hand washable and keeps clean】The cover is hand washable. You can keep it hygienic and clean even if you use it repeatedly. 【Ultra-lightweight】The main body weighs only about 80g. It achieves a comfortable fit that does not interfere with sleep. 【Automatic power off in 10 minutes】A safe design to prevent overuse. The power automatically turns off in 10 minutes, so you don't have to worry about falling asleep. Also prevents overheating and low-temperature burns. 【Commitment to a good night's sleep】Easy adjustment with the adjuster, and a soft rubber band that doesn't hurt your ears, providing a comfortable fit. Cordless, silent design for easy use anywhere. 【How to use】① Press and hold the power button for about 3 seconds. ② Press the power button briefly to switch to your desired temperature setting. ③ The power will automatically turn off after 10 minutes. *You can also turn off the power manually. 【Charging time】About 2 hours (when using a DC5V2A AC adapter). *An AC adapter is not included, so please use your own AC adapter or USB port. *When charging for the first time or after not using it for a long time, the charging time and usage time may differ significantly from the guidelines, but it usually returns to normal after repeating charging and use several times.
