Pope's Piss Valve Oil. I've been threatening this for years! This is my own valve oil - not synthetic, lasts long, works great and will make you smile. I guarantee you'll like it - or a full refund will be issued! 2-fl. Oz. As my friend and fellow hornist Fred Aldrich says: 'Pope's Piss is THE Shi#'.
