Wind Instrument Repair and Maintenance Replacement parts for trumpet wind instruments Approximately 500 trumpet water key corks and spit valve corks. Brand new, unused. Made with natural cork from Portugal. The person who processed and manufactured the only instrument corks in Japan passed away, and these are items they handled. They were well-known in the musical instrument repair industry. Many of their products were supplied to instrument manufacturers such as YAMAHA. Commercially available, clean corks are bleached or have holes filled with powder, but natural corks have stains and holes as they are, so please understand. Sales will be used for the protection of cats. If you wish to purchase, please be sure to include a message. #WindInstrumentRepair #Trumpet #Toranpetto #WaterkeyCork #SpitValveCork #WindBand #JazzTrumpet
