Monster Oil Synthetic Valve Oil - Smoother
Item ID: MOSMOOTHER
Not only will you get the staying power that supports your lazier tendencies, you will get the smoothest action you've ever had from a valve oil. Have an older instrument with worn valves? This will make them behave nicely, and will help to seal the gap created between valve and casing due to your vast years of neglectful and abusive ownership practices. It's so smooth you will forget that your valves even exist.
