Each pad has two buffing sides cushioned by a block of soft foam. One side is for smoothing, and other for shining. Shining is created by a thin and high gloss coating of a proprietary chemical compound, impregnated by buffing. It works well. It changes the nails from dull to high gloss instantly after a few buffs. It amazes your customers, not only by its superior quality, but also the low price which your customers always love.
