Please read the description to the end. This item was given to me. M. Hohner ECHO harmonica, made in Germany, with 10 holes, and a case. - Brand: M. Hohner - Model Name: ECHO - Accessories: Case - Number of holes: 10 - Country of manufacture: Germany Overall, it looks clean at a glance, but this is based on my amateur assessment. Individual perceptions may vary, so please understand this and check the images. The original owner mentioned that it was used very little, and that it produces a clear, beautiful sound. I do not have specialized knowledge, so I cannot answer technical questions. I have done some research, but I'm not sure what the correct price is, so I will do my best to negotiate if you make an offer! Thank you very much.
