The Icing Scrapers are a great tool to get perfectly smooth sides on your cakes. They come in three sizes for any size tiers including extended tiers. The beveled edge can be pressed up against the edges of the Acrylic Disks and will remove cleanly and quickly, any excess buttercream or ganache from the sides of your cake. Even used without the Disks, the Icing Scrapers will make smooth sides on your tiers crisp and clean, and will save you time.
