Create deeply-grooved icing patterns and borders on your cakes, cupcakes, cookies, and pies with this Ateco 51 cross-top pastry tube. Made of durable stainless steel, this tube is rust-resistant and designed to withstand repeated use without bending out of shape. Similar to a closed star tip, this cross-top tip features only 4 points, making this tip perfect for creating eye-catching cross stitching, 4 point stars, and filler piping. It is also compatible with the Ateco 400 coupler and Ateco 407 coupler, making it easy to switch tips without changing the pastry bag.
