Set of 3 gold-plated piston buttons for trumpet Although these are new and unused, they have been stored at home. They are in a bag to prevent discoloration, but they appear slightly discolored. Therefore, I will put them in a different bag before shipping. Please understand that these are not perfect new items, as they have been handled and stored by a person. These are for Yamaha trumpets, but please note that I cannot confirm if they will fit your instrument.
