All these years I've been using the store bought nail polish removers.  They don't work all that well.  They dry out my skin.  Their smell is overwhelming.  A friend introduced me to OPI brands and I'm thrilled with this remover as well as the nail lacquers.  This remover is just fantastic because you can wet a cotton ball, hold it on the nail for a few moments, and then wipe the lacquer away very easily.  A little goes a long way.  This does NOT dry out my skin, it has no overwhelming odor, and works beautifully.  I couldn't be more pleased if I'd swallowed a pink feather duster!  One caveat; be sure that after you use the remover, you wash your hands thoroughly before putting on new nail lacquer because you don't want the residue of any remover on your nails when you put new lacquer on.  It will affect the way that the new layers of lacquer adhere.
