Ultra-Pure All Natural Tuning Slide and Cork Grease

Ultra-Pure All Natural Tuning Slide and Cork Grease does two jobs from one container. On brass instruments it seals and lubricates the tuning slides so they move when you need them to and stay put when you do not, and on woodwinds it keeps the tenon corks supple so joints assemble smoothly instead of tearing. Apply fresh roughly once a week for best results.
