Thank you for viewing this item. This is a mercury sphygmomanometer. It's from about 20 years ago. I bought it when I was a student. I used it for about 2 years, but I didn't use it much because there were many facilities where I could borrow one. The cuff pressure worked properly, and I was able to take measurements. I am selling it because it was left at my parents' house. *There are marks and slight dents on the rubber. Please purchase if you understand that this is a used item stored at home. Notes: ● Please note that there may be slight errors in the measurements depending on the measuring method. ● We cannot respond to claims after purchase, so please purchase with a thorough understanding! ● Compression may occur during packaging. ● Please forgive any wrinkles due to storage or packaging. ● Since the inspection is done by an amateur, please understand that there may be oversight of stains, etc. Also, please refrain from purchasing if you are particularly sensitive to the condition, as it is stored at home. ● Please feel free to ask if you have any questions. *Please refrain from price negotiations to avoid trouble.
