This is a set of two brushes: one More Brush (pink box) and one Mini More Brush (blue box). * The Mini More Brush has a smaller head than the More Brush. These are unused and new, but I am selling them because I no longer need them. For cleaning sensitive oral mucosa: The oral mucosa is delicate. The soft, cotton-like bristles do not damage the mucosa. The spherical brush with bristles all around can remove dirt. The flexible handle provides a stretching effect and helps prevent disuse atrophy. The soft bristles are suitable for those with sensitive mucosa or a tendency to bleed. There is no smoking or pets, but please refrain from purchasing if you are concerned about minor details. Thank you for looking.
