No booklet included. Cushion body only. I haven't used it as a pillow, so I think it's sanitary. It was sold compressed in a small box, so it took quite a while to expand after opening it. There are still some wrinkles. There is some discoloration, please understand that this is a used item. To prevent further wrinkles, I will ship it in an 80-size box.
