This is a stock item. It's a dynamic microphone, a copy of the SM58. It's practically unused, so I think it's in near-new condition. I've disposed of the original box. I've confirmed that it works when connected to an AG03. It has a switch, which is convenient. The sound is lighter than the SM58, but I think it's fine for karaoke or streaming. On the internet, the going price for a new one, including shipping, seems to be around 2400 yen. This item is priced to include shipping, so the price is not negotiable. Thank you for your understanding.
