Thank you for viewing. This slope plays the notes fa, mi, re, and do as a ball rolls down. You can enjoy the movement of the ball while feeling the pleasant, warm sounds unique to wood. When you roll the three colored balls, they play the notes fa, mi, re, and do. Enjoy the warmth of the wood with this high-quality Japanese wooden toy! Please note that there is no box, so the item will be simply packaged. Thank you.
