LOYAL Flower Nails give you the control to create beautiful piped icing flowers. Simply place the Flower Nail between your fingers and rotate as you pipe the flower on the head. Flower nails can also be used as a heat core to prevent high dome cakes. Spray the flower nail with oil and place nail in centre of cake mix with the point end upwards. Once baked, place a board on top of cake, turn cake over and flower nail will pop out.
