This may be a pricey item, but after purchasing it 12 months ago and using it once a week every week, there is about a half bottle of product left.  In the bottle it looks a little darker nude than it is when applied. This is a fast drying product but wait about 10 minutes for the surface to become really hard, then you have a good base for 2 coats of nail polish (wait 10 min between each) and finally (after 10 min) apply Butter London Top Coat.  The base coat and top coat can be purchased in a set on Amazon--good idea.  I use this with China Glaze, OPI, Orly and Butter London with wonderful results--smooth, long lasting and professional looking results.
