Using the Swimways Dive Ring Spinners is super easy. Just drop them into the pool, and they'll spin to the bottom. Kids can play by watching them spin or try to catch them before they reach the bottom. When taking them to the beach or lake, make sure to dry them after use. As for maintenance, just rinse them with clean water and let them dry in a cool place. Remember, these toys are recommended for kids aged 5 or older. Always supervise children when they're using these toys in the water to ensure their safety.
