Please be sure to include a message. Wind instrument repair and maintenance Replacement parts for trumpet wind instruments Approximately 300 trumpet water key corks and spit valve corks. Brand new, unused. Made with genuine Portuguese cork. This is from the stock of a person who was the only one in Japan processing and manufacturing corks for musical instruments, who has passed away. These were items they handled. They were well-known in the musical instrument repair industry. Many of their products were supplied to musical instrument manufacturers such as Yamaha. Commercially available, clean corks are often bleached or have holes filled with powder, but these natural corks have natural blemishes and holes, so please understand. Sales will be used for the protection of stray cats. #WindInstrumentRepair #Trumpet #Toranpetto #WaterkeyCork #SpitValveCork #WindBand #JazzTrumpet
