Used only once and has not been used since. It's an Airweave Pillow Soft. I purchased it as a gift from a hometown tax donation. I used it for only one day, and it didn't suit me, so I'm selling it. *Original price: 22,000 yen Below is the product information from the website: Excellent breathability improves sleep quality with a clean pillow. The head gets the hottest during sleep, and some pillow materials can get stuffy. The core material of the Airweave pillow is made of 90% airfiber®. It is lightweight and highly breathable, and moisture does not accumulate inside. Excellent breathability lowers the core body temperature, creating a comfortable and deep sleep environment. Also, the cover can be washed in the washing machine, and the core material can be easily washed with a shower, so it can always be kept clean. This product is highly recommended for those who sweat a lot during sleep.
