Thank you for viewing. This is a USB rechargeable hot eye mask from "SALUA," a shop with the concept of "body care and healing." It's cordless and easy to use, so the cord won't get in the way while you're sleeping. It has a good feel against the skin and features two levels of temperature adjustment. This item is new, only opened after purchase, and has never been used. However, as it is being sold as a used item, please refrain from purchasing if you are concerned. Instant purchase is OK! (No comment is needed for purchase.)
