My husband got hooked on this sound and bought this steel tongue drum. I'm selling this one because I have another one in a different size. It's about 30cm in diameter and has 13 notes. Height: 15cm It can be used in various situations such as yoga, meditation, relaxation, music therapy, and sessions. Accessories include a dedicated case, strap, mallets (sticks), finger picks, note stickers, and a music book.
