These weird contraptions come from eBay. Personally, I've bought the nose clip and slimming mouthpiece before because it was $1 shipped. Unfortunately, I lost them shortly after my purchase so I don't know if there's any legitimacy to their claims. In the short time I was using them (about 2 weeks), I felt the nose clip didn't do anything. The mouthpiece has potential since I did feel some resistance. This nose clip claims to be able to shape the malleable cartilage in your nose. You're supposed to wear it for 20 minutes a day and you might notice your pudgy, wide, shapeless nose become thinner and sharper. This Japanese contraption is supposed to give the facial muscles around your mouth a workout and slim your jawline. It also claims to make you smile easier. It's called the Noble Slimming Mouthpiece. This face roller claims to roll away your facial fat and increase circulation in the face for a better complexion. This is a ripoff of the T4A appliance. It claims to stop mouth breathing and straighten out mild cases of overcrowding and overjet. I think it may work on growing kids if it does indeed break the habit of mouth breathing but I'm skeptical of it working on adults. Mouth breathing is the worst habit a child can have. It will completely ruin a face if not stopped.
