This is a trombone bell ring I made myself. It will be sent with a hammered finish, although it differs from the photos. Width: 10mm, Thickness: 1.5mm This is a great item for those who want to try a bell cut or to see if a bell cut suits their instrument. Furthermore, it was created with advice from professional trombone players in the Kansai region and well-known repair shops. I am selling the remaining ones after making a large quantity for myself and choosing the best ones. Why not take this opportunity to experience a simulated bell cut?
