Natural sea salt crystals chosen for their optimal range in size and clarity in color. The crystals are treated with our unique coloring process using an individualized combination of candle dyes which adds beauty, depth, and style. We added a tart, zingy lemon scent that makes your lips pucker and your mouth water! You will check your cheek for drops of lemon juice when you smell this wonderful zesty fragrance. Our 16 oz. bag is enough for one oil/melt warmer or a beautiful open dish display. The color may be different from the images shown. Refresher oils not available right now.
