Our Kemket wrist-gripping exercise trainer rings are made from a silicone material that is non-toxic and has no sharp corners, pinching points, or breakable parts, and not fragile.
Note: The Kemket wrist-gripping exercise trainer ring is not a medical device, so it is advisable to consult a healthcare practitioner before using this fitness accessory. This is because the wrist-gripping ring can be used for hand therapy, hand injury rehabilitation, carpal tunnel, stress release, or to improve blood circulation in the forearm.
