This is a Jardinet cornet mouthpiece. The size is 10M, with a slightly shallow cup. This is an old-engraved model that is difficult to find nowadays. It is mostly unused, but there are some slight signs of use and dirt. Please refrain from purchasing if you are sensitive to these details or are looking for a perfect item. There are no accessories such as a box. When shipping, it will be wrapped in bubble wrap. Thank you for viewing.
