I used this for my child for about two months last year. My child mainly used it while lying on their back, and they didn't lick the pillow. After use, I home-cleaned the mat and pillow and stored them at home. There are no obvious stains or damage, but please understand that it was stored by a non-professional. There is no outer box, so I will ship it in the most compact way possible. #BabyGym #moz
