This solid brass mailbox insert is designed to be fully recessed into a pilaster, column or wall. The door is hand crafted of solid brass. The Antique Patina finish comes in natural variations of a powdery blue-green color that darkens slightly over time. The Polished Antique Patina finish can have tones of red, yellow and brown with blue-green patina highlights. Because this is a naturally finished product, no two mailboxes are alike. The top flap opens wide to receive incoming mail. It is designed to be recessed into a wall or column. We suggest when installing into a column out doors that there is an awning to prevent some of the weather elements.
