I am selling a mask used for treating sleep apnea. This type covers both the nose and mouth, making it ideal for those who tend to open their mouths during sleep. It is a size M. The cheek area has a magnetic design for easy removal and attachment. Please consider purchasing. Shipping will be handled using either Rakuraku Mercari Bin or Yu-Yu Mercari Bin, depending on the product size. Please note that the method used may differ from the listing. The mask may be disassembled for shipping to fit within the packaging materials. #CPAP #SleepApneaSyndrome #CPAP #RESMED #ResMed
