This mysterious object sways gently with a doll and arm that wobble when placed, maintaining a delicate balance that makes it difficult to tip over. The metallic sheen is beautiful, making it a great interior accent for your desk or entryway. No batteries are required; a light touch will set it in motion, providing a soothing and refreshing experience. Please refer to the photo's measuring tape for the size. Recommended as a gift. *Please keep out of reach of small children.
