When purchasing Railroad Spikes, it is recommended to buy them in sets of 2 or 4. These spikes are a valuable tool for safeguarding your home and personal space. To activate their full potential, place them on a concrete floor or heat-safe container, then pour rum or Florida Water over them and set them on fire. Once cooled, anoint the spikes with Shield of Protection Oil. They can also be used to create a cross over the entrance of the protected area, or hammered into the four corners of the property for perimeter protection. Sold individually.
