Gym Rings are soft and very strong vinyl mouldedrings that can be used for indoor and outdoor activities. They float so they're also great for the pool and water. Use them for catching and throwing, and fun things like balancing them on your head, holding them on your foot while hopping on the other foot, and what about using them for lazy 8's around your knees!!Colours available red, blue, yellow and green. Sold individually or in a set of 4.
