Thank you very much for viewing. This is a NIKKO metronome (black). I purchased it about 7-8 years ago and only used it a little before putting it away in its box. I have confirmed that it works, and it functions without any problems. There are a few scratches on the side with the winding key, and the speed markings are slightly faded, but otherwise, it is in good condition. The instruction manual is included, and I will ship it in the original box. Please consider using it. Please understand that this is a used item before considering a purchase.
