Our Prairie copper house numbers are sand cast from solid copper at a Kansas City foundry that has been in operation since the 1920's with eco friendly minimum 95% recycled materials. Oil rubbed to help preserve the finish until the natural patina process begins. Numbers are individually hand finished and inspected to guarantee quality. Copper numbers have a tumbled, or burnished, living finish with a desirable naturally distressed surface. A "living finish" has no protective coating. It is designed to change with time and climate. Over time living finishes will vary in color and tone adding to their unique character. Dimensions: approximately 5" tall, 3" wide and 1/4" deep ( the number 1 is 2" wide). Matching slotted silicon bronze screws are included for mounting. Using the example "334", select the number "3" from the drop down list. Click the button that says "Add To Cart". You will be taken to our shopping cart where you can change the quantity of the number "3" to 2 and click on "Update Qty". Then click on the item that is in your shopping cart to return to it and repeat the process for the numbers that you need.
