        Looked Nice Repackaged Damaged
        Box was all taped up. I knew it was a bad sign. Then I drove 35 miles to install it and both corners were bent. Seller is sending damaged items box all taped up without checking. Gonna order a different one now. Gas price in Ca i spent 45 bucks round trip.

          We spent several months considering all of the high end mailbox options available online. After comparing features, sizes, and price, this was the clear winner. Not only was it less than half of the cost of the 'high end' options, but now that I have installed this I feel it is likely the best overall quality as well. The size is perfect, the look is exactly what we wanted, and it functions smoothly. We added special numbers (also available at Home Depot), and paired it with their matching 4" mailbox post. It was a fast and easy install. Would buy this again for sure.

          Big box
          [This review was collected as part of a promotion.] This box is huge! I will not have problems with any of my packages not fitting! It has a very tight closure. It’s made from metal and has some weight to it. My husband had an easy time with install as well

            Modern mailbox perfect for packages!
            [This review was collected as part of a promotion.] This mailbox is one of the nicest boxes Ive seen. It’s sleek and modern and aesthetically pleasing. It is very durable, featuring thick metal and a hammered powder coated finish. As someone who orders frequently online, the size of this box is perfect for small to medium packages. This is super handy because the mailman can put my packages in the box, saving me trips to the post office. The box is very easy to mount with four pre drilled holes. Once the post was concreted in the ground, I mounted the box easily in under 5 minutes. The box features a strong magnet to hold the lid, which requires some force to open. So far, I’ve not had any issues with rain getting into the box as it has a good overhang over the lid. The sides of the box are also large enough to display your name and address clearly. Overall, this is a super nice mailbox that will last a long time.

                Worth the money
                [This review was collected as part of a promotion.] As a product tester, I found the Architectural Mailbox impressively sturdy—solid build, holds up well against weather, and the materials feel premium. Definitely made to last, not flimsy at all.

                  Plenty of space for all of my mail!
                  [This review was collected as part of a promotion.] The Architectural Mailmax mailbox is perfect for receiving packages and large amounts of mail with ease. It is quite easy to attach to the post and holds up very well. I love the modern look and larger red flag. It is well made and will hold up through all the elements. Great secure mailbox that looks amazing.
