This is a Roland Aerophone GO AE-05. I obtained it about 5 years ago through my former workplace's employee benefits program, but I've kept it stored in my room without using it. I opened the outer box this time to take photos for the listing. All accessories are included. In addition, I will include three unused items: an AC charger, headphones, and a guidebook. Although it is new and unused, please refrain from purchasing if you are concerned, as it has been about 5 years since I obtained it. Also, I have intentionally not tested its functionality. Thank you.
