The set includes two cookie cutters and two stamps made of ABS plastic and sells for $15 on the Taco Bell online store.
The cookie cutter and stamp (which can sit inside the cookie cutter) used in conjunction will give your cookies the proper detailing and shape. While you can use them to make whatever cookies you like, you probably want to go with a cookie type that won't expand much during baking to keep the shape and detail.
