Typically purchased in sets of 2 or 4. Railroad Spikes are a powerful tool for protecting your home and space. To heat the spikes and wake up their power, place them on concrete floor or on a heat safe container, pour rum or Florida Water to soak the spikes and set them on fire. Once the fire is done, let them cool down. Once they cool down anoint the spikes with our Protection Condition Oil. You can wrap 2 spikes together to make a cross and then hang the cross over the front door of the space you wish to protect. Or you hammer 4 spikes in the four corners of your home/space to protect the perimeters. Think of hammering a nail to the wall you'd instead hammer down the spikes into the ground in the 4 corners of your property.
