Please be sure to include a message. Wind Instrument Repair and Maintenance Trumpet Replacement and Repair Parts Approximately 500 trumpet water key corks and spit valve corks. Brand new, unused. Made with genuine Portuguese natural 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 selling at a very high price despite wholesaling at a low price, so this is being sold now according to the deceased's will to supply them at a fair value. Sales will end when the stock runs out. The workshop is gone, so some items will disappear completely from the market in the future. Commercially available beautiful 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 activities of protecting cats. Please be sure to communicate via message. #WindInstrumentRepair #Trumpet #Toranpetto #WaterkeyCork #SpitValveCork #BrassBand #JazzTrumpet
