Perfect for piping whipped body butter!

Andrea from Scrupulous Soaps on 10/12/2022

A beautiful tip for piping frosting onto cupcakes easily and quickly. They are durable and easy to wash. They work well with either reusable bags or disposable bags.

Lea V. from Eat It & Beet It, LLC on 04/25/2022

This closed star tip is great for a simple swirl, most of my cupcakes my trademark is a simple swirl. I don't generally pip a lot of frosting on my cupcakes so this tip is ideal.

Patricia F. on 03/20/2022

Works great. It won’t rust. The price is great. I will continue to use ateco products in the near future because they have great quality

Leonel from La Amistad Bakery And Cakes on 12/30/2019

LOVE, this is one of my favorite piping tips. Ever since I first used it in pastry school. It is so versatile and can be used on cakes or cupcakes.

Virginia P. from Sweet Life Bakery on 12/05/2019

These tips are a great investment. They do not have a seam down them so the piping is very smooth, but beware. The steel tips are VERY sharp and can easily rip the bags if you aren't careful.

Sarah G. on 10/14/2019

Great tip! I love the large size, it makes cupcakes look so professional. It is also very easy to clean when finished with your project.

Danielle C. from Conley Baking Co on 10/12/2019

I'm a big fan of Ateco piping tips in general and the 845 closed star tip is no different. It's sturdy so you don't have to worry about the prongs bending easily even if you accidentally drop it or it ends up under something big in the sink. I generally gravitate toward the larger piping tips since I primarily use them for topping cupcakes, but I like having the 845 tip in my toolkit for drop stars and smaller swirls when I don't want as much frosting on certain cupcakes. Overall a good, reliable product.

Xiaolu H. from 6 Bittersweets on 03/09/2019

Ateco is a great brand for decorating tips! We use this to top our cupcakes and we love the result. We would definitely recommend these to anyone in need of decorating tips!

Holly M. from Three Sisters Cake Shop on 02/16/2019

I used these for my Girl Scout Troop. We were earning a baking patch. These worked great, and the girls really enjoyed the activity. They were able to bake and decorate their own cupcakes.

Marlo H. on 01/16/2019

Robert P. from Bobs Bbq And Grill on 09/16/2018

Kala S. from Kays Cupcakes on 07/16/2018

Nice decorating tip for buttercream rosettes. This Ateco 845 #24 Closed Star Piping Tip (August Thomsen) is made of very good material, it's very inexpensive, and does an amazing job...I love it.

Kiera T. from Pretty Cake Box on 05/22/2018

This is a great icing tip for many uses. Perfect for that big pretty icing swirl on top a cupcake. Will definitely order these again!

Lori S. from Bite Of Joy on 01/21/2018

This pastry tube is my go to item when I need to quickly frost items such as decorated cookies. This tip is a perfect size for a nice look and for speedy frosting.

L O. from Fast Casual Cafe on 01/16/2018

This pastry tube has a 7/16" wide tip and features the closed star shape. Pastry chefs love having multiple shapes and widths of tubes to decorate their desserts. This pastry tube is great for decorating cakes, cupcakes, and other desserts. This pastry tube is made by Ateco, a quality manufacturer of pastry bags and tools. We do suggest hand washing these tools.

Brandon G. from Dig & Serve on 12/07/2017

I just used these last week to make a large border around a funnel cake. Came out nicely and made quick work of the decorating.

Hai N. on 12/06/2017

I love this for sweet and simple rose like cupcakes. It folds Ivey around the cupcakes and make a beautiful rose look, my most popular look!

Courtney G. from Courtney's Cakes And Sweet Treats on 11/02/2017

The closed star tube / tip pairs well when writing on cakes and cupcakes. It shoots out a small amount of icing in a closed star shape. It is a favorite of many of our friends and relatives.
