Cork grease is cork grease.This one is no better or worse than other ones.I got this because it's cheap and it works well.This cork grease came just as described.New condition, the correct quantity.Came in very nice packaging that was very thick and protecting.Came right on time.This cork grease does the job, but it's not mint or menthol scented like most cork greases, this one actually smells like grease, and it drives me crazy because I can smell it for the first minute or so after I put together my clarinet (from the mouthpiece cork).Works very well for my clarinet.Great price and shipped to my door!
