Mailbox Modern Square

View our entire collection at https://modern-mailbox.com The attention is in the details and our latest mid-century modern mailbox with the post is sure to please. Our pursuit of offering clean modern lines and hidden hardware is once again the core of our minimalist modern mailbox with post design. Handmade in the USA out of durable aluminum, and finished with a weather-resistant powder-coated finish, our modern mailbox with post will last the test of time (will not rust). Our hidden outgoing mail flag is easily extended by a simple clockwise rotation of the internal knob. Easily rotate counterclockwise to hide when not in use. Paying homage to the mid-century era, the slightly pitched "roof" allows rain and snow to easily fade away on our posted mounted mid-century modern mailbox.

Much larger than I envisioned! But that means small packages will fit without squishing the mail. I also love the locking section and feel more secure now. It’s easy to figure out for anyone to slide mail into the top section and having it fall into the lower part. Very heavy metal. The numbers are magnetic but hold tight to the sides. We are building the post ourselves to save $$ on it. It’s a pretty dynamic piece.. Taimi Gorman. Bellingham, WA. Thu Jul 30 2026
