Set Contents: nanoKEY Studio, USB cables (C to A), outer box. Purchased 4 years ago and used only a little. Stored in a dark place and in beautiful condition. Bluetooth connection works (verified on a 2020 iPad Pro). Instruction manual included. Batteries not included. Currently on a decluttering sale. Other than that, it's a layman's assessment, but I don't see any noticeable stains or scratches. Price reduction and individual sales are not possible, I apologize. Please refrain from purchasing if you are at all concerned about the above condition. Please check the photos and contents, and understand that this is a new/used item before purchasing. Shipping will be compact, so there may be wrinkles, please understand. Also listed on other sites, so it may end early. If you want it, please purchase it as soon as possible. The nanoKEY Studio connects wirelessly in addition to USB. Easily connects to iPad/iPhone instrument apps like KORG Gadget, GarageBand, and music production software on Mac/Windows. Free from troublesome cables, allowing for flexible setup. Also, thorough tuning achieves low latency and high stability.
