Icing combs are a versatile and essential tool for any baker or cake decorator. They are used to create beautiful, textured designs on cakes and other desserts. Icing combs are typically made of plastic or metal, and feature a series of ridges or teeth in varying sizes and shapes.These ridges are used to create intricate patterns and textures on the surface of the cake, such as stripes, waves, or basket weave. Icing combs can also be used to create a smooth, even surface on cakes, helping to eliminate any bumps or unevenness.
