Every once in a while I have inquisitive company come over and ask me what I do for a living. I proceed to pour them a skimpy glass of '61 Lafite Rothschild, put this Gear Shift Wine Stopper back in the bottle and say, "Oh, I sit in my garage and think about surrounding myself with cool car stuff in everything that I touch." When they ask where they can get a stopper like this, I say, "Oh, I know of this great catalog put out by this car loving maniac." Machined out of aluminum, anodized and fitted with three different diameter rubber O-rings to fit a variety of bottle necks. Made exclusively for Griot's Garage. Enjoy the best!
