【Easy-to-Use Cordless, Stress-Free】 Hot eye masks are ideal for promoting restful sleep and relieving eye fatigue. However, about 90% of hot eye masks have cords, which can be a source of stress, such as "the cord gets in the way..." or "it's heavy...". In response to these concerns, Salua's cordless hot eye mask was developed. Not only is it stress-free, but it's also ultra-lightweight at 74g thanks to its thin heater! You can relax without feeling unnecessary irritation. 【2-Level Temperature Adjustment & Auto-Off Timer】 "Adjusting the temperature with a remote control is a hassle..." In response to this concern, the Salua rechargeable eye mask is simple to operate. You can easily adjust the temperature with a single power button on the main unit. There are two adjustment modes: "High" and "Low". The high mode uses a core temperature of 38-50 degrees Celsius and warms you deeply in about 10 minutes. Furthermore, it has an auto-off timer that automatically turns off after 30 minutes. You don't have to worry about forgetting to turn it off before bed, and you can relax both your body and mind... and sleep soundly! 【Comfortable Year-Round with 100% Smooth Silk】 The surface of the eye mask is made of high-quality 100% silk, which is breathable and gentle on the skin. It has a luxurious and rich feel. It's warm in winter and cool and refreshing in summer! It's a cordless eye mask that's easy to use regardless of the season. It fits gently around the eyes, providing excellent light-blocking despite its thinness. It's perfect for naps and breaks when you're concerned about eye strain. By using it as an eye mask without heating, it provides high light-blocking properties, supporting your restful sleep. 【Precautions for Use】 Please refrain from using this product if you: Consult your doctor if you have any concerns about use. ● Those with facial nerve disorders, skin sensory disorders, allergies, skin diseases, and atopic dermatitis, or sensitive skin. ● Those who have had facial implant surgery due to fractures or plastic surgery. ● Infants, children, and the elderly who cannot perceive heat. ● Those with head and ophthalmological sequelae due to traffic accidents, etc. ● Those with or who have had eye diseases, or who have had eye surgery (consult your doctor immediately after LASIK surgery before use). ● Pregnant or breastfeeding women. * Before menstruation, during pregnancy, and during breastfeeding, it is a delicate time when your physical condition is prone to change.
