Grass tips are great for adding fast and easy texture to your baked goods. Decorate spring projects with "grass" or animal themed treats with "fur"... Expand your decorating collection with this handy icing tip. Use with Wilton decorating bags (sold separately). Metal icing tips are made of stainless steel and work with standard piping bags. Pipe multiple pull-out lines for grass and hair. Tips are top-rack dishwasher safe; however, for best results, wash in warm, soapy water before first and after each use.
