"Immediate purchase desired" comment & follow discount 【100 yen OFF】! Please do so quickly! This hot eye mask uses graphene material and is reusable, supporting comfortable sleep. When you turn on the power, the graphene heating film quickly heats up, warming up in less than 10 seconds. It's USB rechargeable and has a built-in 720mAh large-capacity battery, allowing for up to 135 minutes of use. The cord won't get in the way, making it easy to carry when you go out, and you can use it anywhere. You can adjust the temperature to your liking, and it warms you thoroughly with far-infrared rays. It has a 1-hour automatic off timer for peace of mind. This is a beautiful item that I received as a prize and only used once to test its feel. Please check the condition and included wiring in the images. Although it is a beautiful item, it is a used item, and everything in the images is included. No claims and no returns, please. ・Product Name: Graphene Wireless Eye Mask ・Features: Usable as a hot eye mask ・Color: Black ・Size: Free ・Reusability: Reusable ・Accessories: USB charging cable, instruction manual ・Batteries: 1 Lithium-ion battery (included) ・Packing size: 30.9 x 12.1 x 3.9 cm; 300 g ・Manufacturer: Grahope New Materials Technologies Inc.
