Every Iron Stop wind spinner needs a tail. a spiral tail, that is. This clever spinner accessory was made to mesmerize onlookers with its elegant design and eye-catching ball. The single-twisted silver wire creates the effect of the ball moving up and down the strand. The centerpiece of these wind spirals is the blue glass ball that captivates anyone who walks by. As you watch this orb ascend its twisted ladder, you'll swear the movement is real.
