The Otamatone, a unique musical instrument for enjoying sound. - Product Name: Otamatone - Color: Black - Included: Instruction manual - Sound: Purchased 20 years ago and stored at home. I replaced the batteries and checked the operation, but I think the sound is not as clear as it was back then. This is for those who are okay with unstable sound or who can repair it. The instruction manual is made of thick paper, so it will be folded for shipping. The batteries will also be removed (and packaged separately) for shipping. Thank you for your understanding. Thank you for looking.
