This is a Showa-retro era Everest mercury sphygmomanometer. My mother bought it during her student days for practice at home. The actual period of use was only during her student days, so I think it was about 3 years. It's about 40 years old, so there is some fading and scratches on the cuff. Please check the photos. There are no problems with the measurement itself, so I think it can still be used. The box has already been discarded, so it cannot be included. Please understand the condition and purchase.
