Spruce is a blue-toned green holographic polish, and is opaque in approximately two coats. Spruce is named for blue spruce trees, with their beautiful blue-tinged needles. A base coat is recommended with this polish, as it is highly pigmented and highly pigmented polishes can stain.
Spruce is one of two greens in the Winter Holodays collection. Spruce is a blue-toned green, while Evergreen is a true, vivid green. As with many holo polishes of similar color, it's easiest to tell the difference between the two in slightly dimmer indirect light.
Rather than offering sets, purchasing three or more bottles of polish from the Winter Holodays collection in a single order will give a discount of 3.5% on all Winter Holodays collection polishes in the order, which will be reflected in the cart under the line "Winter Holodays collection discount."
