Perfect for built-in or wall-mounted mailboxes, this magnetic mailbox flag is designed for situations where traditional bolt-on flags just won?t work. If your mailbox is surrounded by brick or attached directly to your house, you already know how hard it is to find a flag that fits without damaging the box. Drilling holes not only risks damaging the protective coating, but it also opens the door to rust?something you definitely don?t want on an expensive built-in unit. This design solves those problems. It attaches securely using rare earth magnets, so there?s no need to drill, bolt, or permanently alter your mailbox. You can attach it to the front or side, and when you?re not using it, the flag can be stored inside the mailbox itself. Unlike cheaper flags made from PLA, this one is 3D printed using PETG?a material that holds up to sun, rain, and snow without fading or becoming brittle. It?s a durable, weather-resistant design that?s built to last. The latching mechanism is strong and solid, so the flag won?t flip open or closed in the wind like some of the flimsy competitor models out there. Here?s what makes it stand out: Zero drilling required ? no rust, no damage Rare earth magnets ? strong and secure hold PETG material ? fade-resistant and weatherproof Strong latch mechanism ? won?t accidentally flip Free Shipping ? because that's just fair Crafted with care ? made in my small rural Indiana shop by a former machinist Whether you're in the suburbs or out in the country, if you've got a mailbox that doesn't work with traditional flags, this is the solution. Hand-built with attention to detail and quality you can count on. Support a small business and solve a big annoyance the easy way. Buy with confidence?and get free shipping, too.
