This is one cotton cover for Mitsui Onnetsu Therapy. It is new and unused, but the plastic bag was torn when opening it because it was from a set of two. Please be aware of this before purchasing. Although it is new, please understand that it has been opened once and that the inspection was done by a non-professional. If you are sensitive to such things or are looking for a perfect item, please refrain from purchasing. #MitsuiOnnetsuTherapy
