and safe material: our mouth tape sleep for sleeping is made of high-quality non-woven fabric and adhesive. It can effectively prevent mouth breathing and also leaves air outlet holes to provide you with a safe and comfortable sleep. Prevents mouth breathing: the mouth patch effectively prevents mouth breathing. Mouth breathing can lead to snoring, drooling, dry mouth and many other problems. Longer lasting mouth breathing can also affect your appearance. Improves sleep quality: the mouth tape sleep promotes nasal breathing, which studies have shown to improve the efficiency of oxygenation to the blood and thus allow a sustained deep sleep. Easy to use: clean and dry your lips and surrounding skin before use. The snoring mouth plasters are moderately sticky and do not cause any inconvenience when stuck and leave no glue on the skin after removal.
