As a pictures show, this Fujii Ryoki Physico Therapeutic Medical Instrument is in very nice condition.It is used and shows a bit of wear.  It stands approximately 4 inches tall. The center tube pivots up and down when presure is applied - which is probably the correct way that it is supposed to function. This instrument is used for acupressure and acupuncture purposes. I am selling it more as a collector's item than a medical Aid.
