Thank you for viewing! [3D Design for Excellent Fit] This eye mask is designed to conform to the contours of the face, providing a comfortable fit without being too tight. The excellent fit also provides superior light blocking, making it ideal for sleep. [Memory Sponge Material for Excellent Skin Feel] The inner layer of the eye mask has excellent cushioning and uses soft polyurethane sponge, similar to memory foam, which is soft and breathable. The part that touches the skin uses polyester material, and the silky feel supports comfortable sleep. [Comfortable Sleep Without Pressure on the Eyes] Based on ergonomics, space is designed around the eyes. There is no pressure on the eyes, and you can use it comfortably anywhere. When you feel eye fatigue, put on the eye mask, take a short break, and recover from fatigue. [Adjustable Size with Adjuster Type] Instead of ear hooks, an adjuster-type head band is used, making it possible to adjust the tightness. It is less likely to slip and has a sense of stability, and your ears are less likely to hurt. The size is adjustable, so adults and children can use it. [Earplugs Included for a Wide Range of Uses] In the Shinkansen or on airplanes, the noise is loud, but you can be quiet by using the included earplugs. It is useful when you want to sleep soundly in various environments, such as during a nap during lunch break, night shifts, or a nap in a bright place. 50-21
