Bewitch is a duochrome shimmer top coat, meant for layering over other polishes. It shifts from gold to green, and shows blue at the extreme end of the color range. 

Rather than offering sets, purchasing three or more bottles of polish from the Bespell collection in a single order will give a discount of 3.5% on all Bespell collection polishes in the order, which will be reflected in the cart under the line "Bespell collection discount."
