(^^) Thank you for viewing! I accidentally bought two of the same item, so I'm offering one at a discounted price. Purchased for 3980 yen. ❖ Brand: Salua ❖ Model: USB Rechargeable Eye Mask ❖ Color: Navy ❖ Functions: Hot eye mask, relaxation effect ❖ Features: Ultra-lightweight | Cordless | Comfortable ❖ Target: Age - Children | Adults | ✅【Easy-to-use, Cordless, and Stress-Free】 This hot eye mask is perfect for those seeking a good night's sleep or relief from eye fatigue. About 90% of hot eye masks have cords, which can be a hassle. The Salua hot eye mask is cordless, addressing this issue. It's not only stress-free but also ultra-lightweight at 74g thanks to its thin heater! You can relax without unnecessary irritation. ✅【2-Level Temperature Adjustment & Auto-Off Timer】 Responding to the concern that "adjusting the temperature with a remote is troublesome," 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 core temperature ranges from 38 to 50 degrees Celsius, warming 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, allowing you to relax both your body and mind... and sleep soundly! ✅【Comfortable Year-Round with 100% Silky Smooth Silk】 The surface of the eye mask is made of luxurious 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! This cordless eye mask is easy to use regardless of the season. It fits gently around the eyes and provides excellent light-blocking, despite being thin. It's perfect for naps and breaks when you're concerned about eye strain. Using it as an eye mask without heating provides high light-blocking properties, supporting your restful sleep. 【Precautions for Use】 Please refrain from using if you: Consult your doctor if you have any concerns about use. ● Facial nerve disorders, skin sensory disorders, allergies, skin diseases, and atopic dermatitis, sensitive skin ● Those who have had facial implant surgery due to fractures or plastic surgery ● Infants, children, the elderly, pregnant women, etc.
