Thank you for viewing! #Hanako's Shop ✨Brand new, unused item (operation not confirmed) The hot eye mask provides a comfortable sleep experience and is a reusable, high-performance eye mask. It's 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 degrees, 50 degrees, 55 degrees, and 60 degrees. 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, allowing for complete light blocking. 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. Made with high-quality fabric, it excels in all aspects of touch, durability, breathability, and light blocking, gently enveloping the eyes. 【Hand washable and keeps clean】The cover is hand washable. You can keep it hygienic and clean even after repeated use. 【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 good sleep】Easy adjustment with an adjuster, and a soft rubber band that doesn't hurt the ears, providing a comfortable fit. Cordless, silent design, so you can easily use it anywhere. It's cordless and rechargeable, so you can easily carry it with you during travel, business trips, on airplanes, or trains. 【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 this is usually resolved after repeated charging and use. su214 YOSINA Hot Eye Mask Rechargeable Washable Eye Mask for Sleep Good Sleep Goods Lightweight 99.9% Light Blocking SLEEP MASK
