Hitsuji no Iranai Makura Premium (Pillow That Doesn't Need Sheep Premium) Stored in a cover. Used for about 10 days, but it didn't suit me. It's in good condition with little wear. The cover will not be included for hygiene reasons. The pillow itself seems to be well-made and durable. It can also be washed, so it's hygienic. The original box is not available, so I will carefully pack it at home for shipping. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The following is a product description: ■ A new sensation of soft touch Fully utilizes TPE (thermoplastic elastomer), which is characterized by its softness and resilience. It achieves a soft, floating-on-water feel. The excellent resilience of TPE (thermoplastic elastomer) makes the pillow less likely to sag, and the initial feeling of placing your head on it lasts a long time. ■ Special structure The uniquely developed triangular lattice structure disperses body pressure on the pillow and moderately supports the neck and shoulders. The soft material quickly conforms to the shape of the head. It supports the head while dispersing body pressure, supporting comfortable sleep. It adopts a 3D wave shape with a gentle depression in the center. It makes it easy to turn over and moderately supports the height of the shoulders when lying on your side. ■ Committed to cleanliness! The triangular lattice structure has a hollow interior, achieving breathability. It releases heat that tends to accumulate in the pillow. TPE (thermoplastic elastomer) contains activated carbon with deodorizing effects (*1). Furthermore, the main body can be washed, so if you are concerned about sweat, dirt, or odors, you can easily care for it! You can use it cleanly. Size: Width 54cm, Length 35cm, Height 10cm/8cm
