Iron decorative nails / clavos. Each nail has a primitive rustic feel and look. Made in a primitive style to add uniqueness to antique oriented and farmhouse rooms. Nails are for decorative purposes. Holes should be predrilled to avoid splitting of any wood. Each will measure approximately 3/4" wide on the nail head and the nail is 3" long. There will be some black residue on the nails caused by the forging. This can be wiped away.
