Nails are used for many purposes in magic; one of the best uses is to nail something or write your wishes on a wax candle.
Use the type of nail that best suits your intent: a gold brass nail is used for prosperity and healing, a copper nail for love work and energy transfer, an iron for grounding, protection and demonstration, and nickel for problem-solving, justice. … and powers and rusty coffin nails are used to harm the enemy.
These nails are slightly thicker than a pencil and large enough to be used as small, easy-to-handle rail picks. Douse them with Powerful Protection oil and nail one to each corner of your property for a spiritual electric fence to keep villains, homeowners, or banks out of your property.
