It's beautiful but quite disppointed that it arrived dented and there is paint missing where it is dented. The dent also created a gap on the from of the mailbox. Also, the description said it came with the post. After waiting over a month for the mailbox to arrive, it arrived without the post and dented. Other than that, the box is offers a clean and modern aesthetic.. Katia. Doral, FL. Tue Sep 23 2025
