The Icing Tube Tip # 403 large Ribbon. A ribbon piping tip is a specialized nozzle, often made of stainless steel and identified by a unique pattern cut into one end, used to create ribbon-like, fluted, or ruffled frosting effects on cakes and other desserts.

These tips are used for decorative borders, flower petals, and elegant vintage designs by wiggling the piping bag up and down as you move it across the surface of the dessert.
