Please note that this item may be canceled due to circumstances. This is a 51C4 mouthpiece for trombone and euphonium made by Schilke. I kept it as a spare. Although listed as (like new), it has only been test-played, so I think it's in beautiful condition. However, please understand that it has been stored by an individual and is based on my personal opinion. The photos have been processed for lighting and detail. [Mouthpiece] ◯ Schilke, Schilke, Large Shank ◯ Inner diameter 25.63mm Please check the catalog to prevent any problems. I try to ship as quickly as possible, but it's difficult on weekdays, so shipping will be on weekends. Thank you for your understanding. #Trombone #Euphonium
