Frequently Asked Questions

What is the difference between an open star and closed star piping tip?

An open star tip has separated teeth at the opening, producing a more relaxed, textured swirl. A closed star tip has teeth that touch, creating tighter, more defined ridges. Open star tips like the 21 are ideal for soft rosettes and shells.

Do I need a coupler to use this piping tip?

A coupler allows you to swap tips without changing the piping bag. The Loyal size 21 tip fits standard large couplers. For single-use piping, you can also drop it directly into a disposable piping bag.
