I have been seeing these flow rings around and wasn't sure what they are or what they do but I did know my kids wanted them. This one is a great deal because you get two sets of flow rings, They are metallic rainbowed color. They are interlocking rings that you play with. It is also like another fidget toy. This one to me is more fun and cooler looking though. I like to place on my wrist and let it flow from one hand to the other. It does a fun spiral rotation and is so mesmerizing to watch. There are tricks you can do with them and cool designs to watch. They can even be used as a decor item if you want. They are metal rings and are very sturdy and durable for kids of all ages. They make great birthday and Christmas gifts. So get yours today! #rankboosterreview #sponsored #INSIST https://www.amazon.com/INSIST-Kinetic-Interactive-Gravity-Rainbow/dp/B07C837MH1
