This is the third collaboration, Spartanology, between MYSTERY RANCH and Carryology. I purchased it new at MYSTERY RANCH TOKYO and used it about three times a week for about six months. There are some scratches from use, and some discoloration on the metal fittings. There is no damage. The patch is unused.
