I will sell at this price until December. This is a Christmas limited-time price reduction. I used this for 3 years when I was in junior high school. After that, I stored it in a dark place for about 2 years. The microphone is included, but the box is not. Both the tuner and microphone have been tested and are working properly. When shipping, I will remove the batteries just in case. If you would like the strap that came with the purchase, I will include it for free, so please let me know. Instant purchase is OK.
