Thank you! This is a high-precision polytune clip tuner! It's very responsive and one of the easiest to use. It's in beautiful condition. I was using it until recently, so there are no problems with normal operation. I will not include batteries when shipping, so please prepare a CR2032 battery yourself when you purchase! - Model name: polytune - Color: White - Type: Tuner Please refrain from purchasing if you are concerned, as this is a used item.
