Earlham Lipstick style Woodwind cork grease is a lip balm-like grease for woodwind and reed instruments such as saxophones, clarinets, and oboes.
This professional quality grease is used on the corks to make putting the instrument together possible without damaging the cork and therefore possibly damaging the instrument itself.

Earlham cork grease also acts as a preservative, keeping the wooden cork moist and thick, in turn ensuring a good seal between parts of the instrument.
