Each artwork is finished with 4 hand-forged nails. The traditional nails are handcrafted, making each nail unique. These nails provide the artwork with an authentic look and allow the print to float within the frame. The elegant tin-finish emphasizes the iron’s texture. The finish penetrates deeply into the metal, resulting in unparalleled contrast, texture, and color. The nail has a head size of 12-16mm, a thickness of 4-5mm, and a length of 65mm.
