Hot Eye Mask, Rechargeable, 3-Level Temperature Adjustment, 20min Auto-Off, Cordless, Gel Pad, Earplugs Included Brand new, unused. ◯ 3-level temperature adjustment: "gentle, warm, firm" Freely select your preferred heat level! The biggest appeal is the ability to freely choose the heat level according to the delicate condition of your eyes and your desired level of relaxation. From a gentle warmth that invites a comfortable sleep with "gentle" to a full-fledged eye care that warms deeply from within with "firm," this hot eye mask allows you to achieve high-quality eye refreshment with the optimal temperature according to the fatigue of your eyes on that day. ◯ Zero-light design × Silk touch It combines "silk touch," where a high-quality silk material gently envelops the delicate eye area, and "complete blackout" with a zero-light design. The soft silk with little friction and irritation provides a comfortable fit without burdening the skin. Furthermore, by reproducing a "pitch-black space" with complete blackout that doesn't allow even a little light, the rechargeable hot eye mask supports high-quality rest and sleep, both in the mornings and nights when you can't fall asleep, by deeply relaxing the brain. ◯ Equipped with a 20-minute auto-off function It is equipped with a "20-minute auto-off function," so you can use it with peace of mind without worrying about leaving it on. When the optimal time (about 20 minutes) for warming the eyes passes, the power automatically turns off, so it is safe even if you fall asleep. This not only prevents excessive heating of the eyes but also saves unnecessary power consumption, making it an excellent rechargeable hot eye mask that also saves on electricity bills. ◯ Cordless design × Washable silk cover USB rechargeable, with no stress of "cords getting in the way." The "cordless design" allows for comfortable eye care in any position, anywhere. Furthermore, the skin-friendly high-quality silk cover can be removed and washed, so you can always keep your eye care products, which tend to accumulate sweat and sebum, clean. ◯ Earplugs & cooling gel pad included "Earplugs" and a "cooling gel pad" that can be used separately from the heat care are included. By shutting out surrounding noise with earplugs and completely blocking light and sound stimulation, the quality of rest is dramatically improved. Also, by using the included cooling gel pad, you can not only warm but also cool down for eye care, making it a multifunctional set that realizes total eye care on both warm and cold sides and a high-quality sleep environment.
