Parchment triangles were the original piping bag for pastry chefs and are still used by many today.
Parchment triangles are lightweight, easy to fold into a bag, and completely disposable.
Parchment triangles are a very convenient way to keep track of several colors when decorating your cake, especially when dealing with small amounts of colored icing.
Parchment pieces are 15 x 15 x 20 inches.
These can also hold piping gel and melted chocolate, too.
Grease resitant coating on the parchment helps prevent any seeping.
