ONETONE Roll Piano 61 Keys OTR-61

This is a 61-key roll-up piano.
I am selling it because I haven't used it recently.
I checked it before listing, and all keys produced sound.
The instruction manual, pedal, and charging cord are included.
Due to the material, dust tends to stick to the main unit. I have removed as much as possible, but please understand that some may remain.
Please consider purchasing with the understanding that this is a personally stored item.
Also, I have not mastered all of its functions, so I may not be able to answer questions about detailed features. Please understand.
