Pastry bags with pastry tips are the utensils you will need for many cake decorating ideas. Perfect for icing, shaping meringues and filling donuts with jelly and custard, a pastry bag is simple to use yet highly versatile and practical. We carry pastry bags made of nylon and cotton that are reusable, many of which are dishwasher safe; and disposable plastic pastry bags that can help you avoid a messy clean up job.
