Certain folk-magic customs have long used a nail, driven into wood, earth, or a symbolic object, as an act of binding, banishing, or protection - the same instinct behind nailing a horseshoe over a door, given a sharper, more deliberate edge. "Coffin nail" is the customary name given to this particular style of iron nail within that practice; it does not mean the nails included here were pulled from an actual coffin, and no such claim is made about their origin.
This listing includes five nails, each 1.5 inches long, sized for the kind of work practitioners typically reach for them: pressed into a poppet, dropped into a spell jar or bottle alongside other curios, or driven into the ground or a doorframe as part of a banishing working. A general usage guide ships with the set for anyone new to this particular curio, covering the most common ways it's incorporated into a working.
Coffin nails are most often combined with other customary ingredients rather than used alone - black salt, graveyard dirt, or a name paper are common companions in binding and banishing jars, and a fuller range of curios and spell supplies for that kind of work sits alongside this listing in the same collection.
As with any folk-magic curio, whatever effect using these nails has on a working's outcome is a matter of personal and customary belief, not a demonstrated result, and this item is not a means of causing real harm to another person. It is sold and described here strictly as a symbolic, ritual object, not a weapon or a tool for physical harm.
Because these are genuine pointed metal nails rather than a decorative prop, they should be stored securely and kept away from children and pets, the same as any small sharp object kept in the home. Handled that way, a single set of five is enough for several separate workings.
