Yamaha 合成調音管潤滑油脂
Yamaha synthetic tuning slide grease is a premium synthetic tuning slide grease in a small round container that keeps your tuning slides moving smoothly in a wide range of temperatures and weather conditions, with an added corrosion inhibitor that gives extra protection to the instrument’s metal. This thicker formula is ideal for main tuning slides or any slides that need to be smooth without slipping.
