Whether you want to bake a bottle of soda pop, sparkling water, or beer, the 4.5″ Bottle Cookie Cutter will help you get the job done. Bottle cookies make great additions to any sporting event party, 21st birthday party, or just to go with root beer floats. Made of tin-plated steel, this cookie cutter is durable, food-safe, and easy to clean, but we recommend washing it by hand to prevent rusting and damage.
