Cookie Cutters are 3D printed at the time of order. They are not made of metal. We generally recommend cutters 3 inch and smaller for fondant or décor, 4 inch and above for cookies. This is just a rule of thumb, for specific sizing details (if not listed), please contact us. All cookie cutters in the main image will be included. Cookie cutters are NOT dishwasher safe, but can be washed in warm water. Color may vary , for a specific color please contact us.
