This is an Emeo digital saxophone. The color is the Vintage type of the initial model, which is no longer sold. It works by outputting sound via USB or Bluetooth through a PC. The manual is also available, so please check the official Emeo website for details. https://www.emeomusic.com I personally imported this from Israel around 2021. The list price was $1550, which is about 230,000 to 240,000 yen at the current exchange rate. Please be aware that there are some areas with dust due to home storage, so please be careful if you are sensitive to this. Returns are not accepted, but we are open to price negotiations and questions.
