Practice equipment for French horn. Non-pressure device. - Product Name: Methodischer Übungsadapter Horn - Model Number: Nr. 60306 - Country of Manufacture: Germany - Brand Name: MIGMA eG Markenkeirchen Thank you for viewing. I purchased this about 20 years ago and used it for practice for a while to suppress pressure. After using it a few times after purchase, I stored it at home for a long time. There are no noticeable scratches on the main body, but since it is used, please refrain from purchasing if you are sensitive to such things. Also, please note that the box is somewhat damaged as shown in the image. I will ship as soon as possible, but I may keep you waiting a little due to work circumstances. * No price negotiations
