Review: Best Mailbox - Over the years, this has been our favorite mailbox. It is sturdy and durable. Perfect size. Flag goes up easily and stays in place. The best part is that it closes tightly and secure. Door is never hanging open. Mail stays dry.
Review: WELL worth the $$$ - This should be the last mailbox this house will ever need! Very thick metal, paint is solid, rivets are stainless and the door has a neodynium magnet! BRILLIANT! Can't wait for the neighbors reactions!
