New, unused, unopened. The purchase price was 1,856 yen, but I am selling it to declutter. The following product description is quoted from the description at the time of purchase. Dental Mirror with LED Light, Dental Mirror, Oral Care, Bad Breath/Plaque Check, Dental Mirror, Home Dental Mirror with LED Light, Dental Mirror, Oral Care, Bad Breath/Plaque Check, Dental Mirror, Home Use, Self-Care for Teeth, Self-Care for Teeth [Equipped with High-Brightness LED Light] The inside of the mouth is darker the further back you go, and there are many parts that are difficult to see with a normal mirror. The dental mirror has a built-in high-brightness LED, which brightly illuminates the back teeth and the back of the teeth, allowing you to check them thoroughly. You won't miss small stains or problems, giving you peace of mind for your daily self-checks. There is no need to prepare an additional flashlight. [Anti-Fog Nano Coating] Many people worry that "the mirror will fog up and I won't be able to see it" during use. The dental mirror has a nano-coating on the mirror surface to prevent fogging and ensure a clear view at all times. Checking for plaque and tartar is also smooth, and you can clearly observe even the smallest details. It comfortably supports regular self-checks. [Design that considers ease of use] Because it is used daily, we have also focused on ease of operation. The non-slip processing allows you to hold it stably even if you have sweaty hands, reducing the worry of accidentally dropping it. Furthermore, battery replacement does not require a screwdriver like conventional products, and can be easily opened and closed by simply sliding it with your finger. The design allows for comfortable use and supports continuous self-care. [Precautions for use] Be sure to remove the protective film attached to the mirror surface before use. When cleaning, rinse only the lens part lightly with water, and be careful not to get water on the LED light or the part above it.
