This is a KORG NANOKONTROL2 MIDI controller. I opened it for confirmation, but have kept it carefully stored at home since then. Therefore, the condition is very good. I have confirmed its operation on WINDOWS 10 and MACOS 10.13.6! The included items are the main unit, outer box, USB cable, instruction manual, and serial code, a complete set. I will pack it carefully and ship it immediately, so thank you! ★ Immediate purchase is OK. ★ Please check the condition. ★ Everything in the photos is included. ★ If you have any questions, please ask before purchasing.
