These Medieval Iron Clavos serve as round decorative nail heads for doors, cabinets, gates, and furniture. Each piece is formed from solid cast iron, with a dense structure suitable for accent work. The smooth round head has a dark matte finish that gives an elegant appearance when installed. The overall length measures 3 cm (1 1/8 in), and the head width measures 2.5 cm (1 in). A matte black protective coating is applied to help reduce surface rust and give weather resistance under normal conditions. Supplied as a set of 6, these antique-style rustic iron studs are intended for decorative and practical installation into wooden surfaces.
