These all-in-one disposable decorating bags are so simple to use. The tip is attached to the bag, so there's no fitting or cutting, just fill with your favorite frosting and you're ready to go. The open star tip pipes pretty rosettes, stars, swirls and more. Great for decorating cakes, cupcakes or brownies. And since these combo piping bags and tips are disposable, there's no messy cleanup required. Just ice your treats, then toss when you're done!
