Thank you for viewing! ❤️ Price negotiation → Highly welcome ⭐️ First come, first served ⭐️ Initial defect warranty included ※ The product has been opened once for product photography. Please understand. The chin support is an anti-snoring device designed to prevent mouth opening during sleep and promote nasal breathing. It is made of soft, stretchy materials such as neoprene and can be adjusted to fit the head size with hook-and-loop fasteners (Velcro). Promotes nasal breathing: By gently securing the chin, it prevents mouth breathing and supports natural nasal breathing. Reduces snoring: In cases of snoring caused by mouth breathing (throat snoring), it can help to secure the airway, which may reduce snoring sounds. Dry mouth and throat prevention: By keeping the mouth closed, it prevents dryness of the mouth and throat during sleep. Comfortable fit: Made with breathable materials and adjustable sizing for a comfortable fit. ❤️ I have many other items for sale! ↓ Further discounts are available for bulk purchases (*^^*) ↓ #YUKA'sShop Management number: 19-1148$$580
