Like the Mystic crystals these polymer pearls are created by simply adding water. This causes them to expand into perfect miniature spheres. Use them to add some extra color to your decorating scheme. They are available in pink, aqua, sapphire blue, black or clear. Use separately or mix colors in one vase for a stellar effect! One package will create approximately 5.75L or 1.5 gallons of hydrated water pearls.
