Steelpan, approximately 60cm in diameter. I fell in love with it in Bali 10 years ago and bought it. However, I've played it less than 10 times. Please check the photos as the inside of the case is partially discolored. The last photo is of the shop staff who gave a demonstration when I bought it. Please use it to check the size. ★Pick-up preferred (Wako City, Asaka City, Shiki City in Saitama Prefecture, Nerima Ward, Itabashi Ward in Tokyo) Please consult if you wish to have it shipped.
