Pocket-sized synthesizer I received from a friend. Body only. Simple operation has been confirmed. Sound output is working. Free shipping via Rakuraku Mercari delivery. I cleaned it as much as possible, but there may still be some remaining dirt. Please refrain from purchasing if you are concerned. It has been some time since the purchase, and there may be crackling noises when turning the knobs or moving the jacks. Also, please understand that this is a used item and is NCNR (No Claims, No Returns). No complaints, no returns.
