The wrapping around the shaft is colored by a real 24-karat gold "fuming" process. The gold is in the glass so it will never fade or wear off and it's completely safe. It's approximately 7 inches in length and 1 inch in diameter with the spiral wrapping adding approximately 1/4 inch to the diameter of the shaft. The head is clear and smooth measuring approximately 1 2/5 inches in diameter. The other end features a "double ball" handle that are approximately 1 1/4 inches in diameter and are easy to hold and control this piece. Both of the marbles are crystal clear and smooth.
