Wind instrument repair and maintenance Replacement parts for trumpet wind instruments Approximately 2000 water key corks/ spit valve corks for trumpets. 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. They were well-known in the musical instrument repair industry. Many of their products were supplied to musical instrument manufacturers such as YA. They were being sold at a very high price despite being wholesaled at a low price, so this is being sold according to the deceased's will to supply them at their appropriate value. Sales will end when stock runs out. The workshop is gone, so some items will disappear completely from the market in the future. 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 proceeds will be used for the protection of stray cats. Please purchase soon as sales will end when stock runs out. #WindInstrumentRepair #Trumpet #Toranpetto #WaterkeyCork #SpitValveCork #WindBand #JazzTrumpet
