I am listing this Musonic Ltd of St Albans Herts cassette head cleaner. It cleans cassette heads. For those under 40 cassettes is what one listened to music on and you had to keep the head clean. Old School stuff. No idea if it has any head cleaning abilities left, but someone may want it if only to put in a museum.
Collection W4 off Acton Lane. I operate a fair offer policy so please don't get the hump if I don't respond immediately (and I do try and respond to everyone!)
