The Authentic Bronze Collection was inspired by the rugged beauty of the American outdoors, and is made of 100% solid bronze, with rock solid craftsmanship. The applied bronze patina finish is designed to wear off slowly over time and this will further enhance the beauty of the letter slot, by exposing the natural shades of the oxidizing bronze. This is a living finish. The Ornate Letter Slot reads "LETTERS" in the front, and comes with a matching backplate for the interior side of your wall or door. Letter Slot Dimension: 10"w x 3"h overall. Cut-out Dimension: 8"w x 2 1/4"h (approximately). The incoming mail flap LIFTS UP to receive mail. This item ships within 72 hours, when in stock.
