Description
A star tip for swirls, rosettes and shell borders
The 1M is the large open star tip — the shape that turns one squeeze into a ridged swirl. Unlike a closed star, the points stand apart, so the icing comes out in sharp, well-defined ribs with deep grooves between them. That is what makes the classic cupcake swirl, the rosette, and the shell border read as crisp edges instead of a soft mound. The mouth is wide at 13 mm, so stiff buttercream and ganache pass through without fighting the bag.

What you can pipe with it
- Cupcake and cake swirls in one steady squeeze
- Rosettes and drop flowers
- Shell and rope borders around cake sides
- Ridged dots, stars and small piped mounds
- Two-tone swirls when you load a two-colour bag
- Whipped cream, meringue, mousse and stiff buttercream
The open star does not suit writing or smooth filling — for those, pair it with the 1A large round tip. For a tighter, more closed rib use a closed star such as the 1G 10-ray, and for a shallower 6-ray profile the 2D. Our full star and round tip range can be mixed in one order.
Who buys it
Bakeries, cake shops, catering kitchens and distributors who decorate in volume. The 1M is the single tip most decorative kitchens replace first — it covers cupcakes, layer-cake sides and rosettes without switching tools, and it is the tip most often quoted by name by retail buyers building a starter assortment.

Frequently asked questions
What is the difference between an open star and a closed star tip?
A closed star has points that meet at the tip, producing tighter, more closed ribs. An open star such as the 1M has points that stand apart, so the ridges are sharper and further apart — which is why it is the standard choice for cupcake swirls and rosettes.
What is the difference between 1M and 2D?
Both are star tips, but 1M is the larger, more open star used for swirls and rosettes, while 2D is a shallower 6-ray closed star for tighter, more defined edges. Most kitchens keep both.
Does it fit a standard coupler and bag?
Yes. It seats on a standard medium coupler and works with standard reusable or disposable bags.
What is the minimum order?
12 pcs per SKU as a trial quantity. Mixed-SKU orders can be combined from 120 pcs, and tier pricing starts at 1,000 pcs.
Can you print our logo?
Yes. Laser engraving or silk-screen printing from 500 pcs, with your own retail packaging if needed.
