Lustre Dusting Colouring

In its basic form, edible luster dust derives from an exceptionally fine, food-safe powder used to dust over icing to create a fabulous iridescent shimmer. Think of the product as an eye shadow for food! Plus, it comes in various fantastic colors, including gold, silver, and stunning glittery rainbow colors.
