For sale are two high-performance golf shafts: MITSUBISHI CHEMICAL Diamana R80 and R70. FLEX-X I was planning to use these, but the flex doesn't suit me anymore, so I'm selling them. These are unused Mitsubishi Diamana driver shafts. Although unused, please refrain from purchasing if you are overly concerned, as they have been stored by a private individual. Please understand that there may be insufficient explanations or oversights due to this being a private sale. Returns and refunds will not be accepted.
