▲ The box is oversized, so I will ship the item without the box. I purchased this last year as a spare and have been storing it at home. The opened one in the photo is the eye mask I am currently using. It fits well and is comfortable to wear. ★ The item for sale is unused. Three-dimensional shape and adjustable strap. This eye mask uses terahertz waves to relieve muscle tension and stiffness, supporting comfortable sleep. Color: Black Size: Free (adjustable strap) Retail price: ¥2,800 (excluding tax)
