New And Features: 1. Ensure Nose Breathing - Habitual mouth breathing during sleep can cause changes in facial structure, snoring, sleep apnea, non-compliance with CPAP, and even cause oral and respiratory diseases. This Sleep Strips safely keep your mouth closed, making it easy and effective to keep your nose breathing while you sleep. 2. Unique Mouth Shape Design -This mouth sleep strips has unique design that surrounds the mouth and does not cover your mouth, allowing you to use it without claustrophobia. When the mouth patch is on your mouth, it will stimulate your skin and trigger a neural response in the facial muscles. This will remind you to close your mouth gently and breathe through your nose.
