※ This product is not a medical device. I received this for my child at work, but it was hardly used. It can correct crossbite, the position of the mouth, and the tongue. I have a medical ultrasonic cleaner at home, so I will clean it in the machine before shipping. ※ The box is slightly crushed. 　 There is a 2mm tear on the edge of the shield. 　 (It was like that from the beginning) #Crossbite #MooShield #Orthodontics #Mouthpiece
