In response to concerns like "The light from the operation buttons is too bright for the person sleeping next to me," the Mycarbon hot eye mask automatically dims the light after 30 seconds, preventing disturbance to the sleep of family members sleeping nearby. 【5-Level Temperature Adjustment & Auto-Off Timer】 40℃－45℃-50℃-55℃-60℃, 5 temperature modes are selectable. Compared to conventional products with 2 temperature levels, this product allows you to find the temperature that suits you better by finely dividing the temperature. With an auto-off timer function, the power automatically turns off after 15 minutes. You don't have to worry about forgetting to turn it off before going to sleep. Note: The default level order is 4-5-1-2-3, and when using it for the first time, it is recommended to start with the 1st level temperature and gradually get used to increasing the temperature. 【USB Rechargeable & Wireless】 Being rechargeable, it's very convenient to use immediately after lying down in bed just before going to sleep. With a 1200mAh large-capacity battery, it can be used continuously for 5 times (at level 1) on a full charge. The wired type of conventional products can feel like the cord gets in the way when used while sleeping, so this product's wireless type is easier to use. 【100% Silk & Adjustable Band】 Made of skin-friendly silk, it's warm in winter and cool in summer, providing a comfortable sleep experience. The band is adjustable and can be used within the range of 19cm-35cm. The cover is removable and can be washed separately.
