This is a kitten cover for a Nemurie doll. It was originally gray, but may be slightly darkened. Please understand that this is a used item before purchasing. I also have the main body, but it didn't work even after changing the batteries, so this is just the kitten. If you want the box, it will be 1600 yen, so please let me know. [Nemurie Product Overview] Based on research that suggests "there is a trigger to rest the body in the heartbeat felt in infancy," this relaxation item was jointly developed with sleep specialists. A machine inside the stuffed animal creates vibrations like a human heartbeat, guiding the person into a relaxed state.
