Ateco Tube Tip # 30 Closed Star is a professional stainless steel piping tip used in baking to create deeply grooved, defined decorations like shells, rosettes, stars, and fleur-de-lis on cakes, cupcakes, and cookies, producing a textured, ruffled look distinct from that of open star tips.

• It’s a versatile tool for adding borders and swirls, and it fits standard piping bags and couplers.
