【The Reborn, Popular Eye Mask】 The Salua hot eye mask, with over 450,000 units sold, has been renewed as the new brand "nerugoo." Inspired by customer feedback, it has been upgraded to be even more comfortable and user-friendly as a sleep aid. 【Economical! Rechargeable for Daily Use】 The perfect hot eye mask for relaxation. Ideal for sleep, short naps, or as a sleep aid during travel. It's rechargeable, so you can use it anytime, anywhere, whenever you feel eye fatigue. 【3-Level Temperature Adjustment & Auto-Off Function】 Temperature can be adjusted with a single power button on the main unit. There are three adjustment modes: "High," "Medium," and "Low." It also has a convenient auto-off timer that turns off automatically after 30 minutes. 【Designed for a Good Night's Sleep】 To improve skin contact, mechanical parts such as zippers and buttons have been minimized. The unique "nerugoo SILK" technique is used to achieve a skin-like touch that feels like it's clinging to your skin. 【Unisex Eye Mask, Adjustable with Adjuster】 It's free-size and adjustable, making it perfect as a gift for people of all ages and genders. I've used it a few times, but I no longer need it, so I'm selling it. The functions work perfectly. All accessories are included. #EyeMask #HotEyeMask #GoodSleep #SleepAids #Sleep #nerugoo #Nerugoo #Rakuten
