This is a wet cleaner for cassette tape decks. It can clean the heads and the transport system at the same time. The cleaning fluid is about half full. This item has been stored for a long time, so it is unknown whether it can still be used, but I haven't been able to confirm its functionality due to lack of an environment to test it. Please consider purchasing with the understanding that it may not work. Everything in the photos is included. #AudioAccessories #CassetteTape #HeadCleaner
