Flex Massager Stored at home. It's old, but works without any problems. Using the principle of leverage, it allows even those with little strength to massage easily. It's a lightweight and compact kneading device, effective for those with stubborn shoulder stiffness. The handle is foldable, so it doesn't take up much storage space. A sturdy construction from the Showa era. A powerful muscle-relieving device that you don't see these days. Photos 4, 5, and 6 are from the internet. Please see them as reference photos. Would anyone like to use it? Thank you very much.
