Skull Self-Correction Exercise This is the DVD for "SKULL CONTROL." I've watched it twice. As shown in the fourth photo, there is a small spot of dirt? on the DVD package. Other than that, there are no scratches or stains, and it's in good condition. The DVD can also be viewed without any problems. The mouthpiece is not included. Please note that this is only the sale of the DVD. With this exercise, the line between my upper and lower front teeth became straight (before, they were misaligned, and didn't form a single line), and my cheeks also became slimmer.
