Please be sure to include a message. This is for trumpet replacement and repair parts. Approximately 2000 trumpet water key corks (spit valve corks), about 1000 in each of 2 bags. Brand new, unused. Made with genuine Portuguese cork. The cork size is the same as YAMAHA. Wind instrument repair, wind instrument maintenance. This item was handled by the only person in Japan who processed and manufactured corks for musical instruments, who has passed away. He was a well-known figure in the musical instrument repair industry. Many of his products were supplied to musical instrument manufacturers such as YA. We are selling these items 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 these natural corks have stains and holes as they are, so please understand. The proceeds will be used for the activities of protecting cats. Unfortunately, there were people who immediately resold the items at a low price on Amazon, so we have stated that resale is prohibited. #WindInstrumentRepair #Trumpet #Toranpetto #WaterkeyCork #SpitValveCork #WindBand #JazzTrumpet
