Please comment if you'd like to negotiate the price. ☺️ An organic cover pillow that cools the brain for fast and deep sleep. Originally priced at 37,400 yen on Amazon. This was won at a company year-end party. Purchased from Amazon. The contents were checked at the event by opening the pillow and cover bags, but it has never been used. I am selling it because I originally use a made-to-order makurabo pillow. Please understand that this item has been handled by someone else and has been opened before purchasing. - Brand: BRAIN SLEEP - Model Name: BRAIN SLEEP PILLOW STANDARD - Cover Material: Organic Sleep Midnight Navy - Features: Cools the brain for fast and deep sleep - Sleep Quality: Lowers the "brain temperature" that determines sleep quality Thank you for looking.
