i-Sleep 3D Eye Mask Brand new, unused. Will be shipped in a bag as is. #KEN_BOX From the following site: Conventional eye masks enhance light-blocking by tightly adhering to the face. However, this can also increase pressure on the eyeballs, leading to a feeling of tightness. To solve this problem, the i-Sleep "3D EYE MASK" was developed. By creating a dome-shaped three-dimensional structure for the eye area, a space is created between the eyelids and the eye mask. To ensure comfortable sleep even during long periods of wear, a smooth and skin-friendly material is used. It also has excellent cushioning properties, with a softness and fluffiness similar to memory foam, supporting a comfortable sleep. The elastic strap uses a Velcro fastener of about 10cm. The length can be easily adjusted, so it fits perfectly to any head size, regardless of gender. When carrying it, it can be folded compactly for storage. It's lightweight and made of a material that doesn't easily lose its shape, so it can be stored smartly in a pouch. You won't even notice the eye mask when traveling, where luggage tends to increase. Size: Free size (unisex) / Weight: Approximately 20g
