These mouthpieces have all sat for a while and are pretty tarnished (an easy fix with some silver polish and warm water). They are part of my personal collection. They will all be shipped wrapped individually in bubble wrap via USPS. All but 10 of the mouthpieces are marked with a name-brand from highly reputable manufacturers. Lot is sold "AS IS" with no partial returns or discounts.List of Mouthpieces: Trombone:Yamaha Japan 48Vincent Bach Corp.
