Thank you for viewing. This is a Hohner Blues Harp harmonica, made of metal and plastic, with a blue case. It's an old item, but it still produces sound. The key is unknown as the sticker has come off. The black plastic inside the case also comes out. There are scratches and some rust, but I think it has a nice retro feel. - Brand: Hohner - Model Name: Blues Harp - Key: Unknown - Case Color: Blue - Material: Metal and Plastic We will use recycled materials for packaging.
