Red mailbox flags are made of sturdy metal and can withstand hot and cold climates, resist fading from sunlight, and offer a long lifespan. Easy to assemble and install: These red mailbox flags are not universal; ensure your external mailbox has two flag holes—one larger hole measuring 1.2 cm in diameter and one smaller hole measuring 0.6 cm in diameter—otherwise installation may not be possible.

Gravity design: The mailbox flag rises and stands upright by gravity, ensuring smooth operation. Once raised, the flag is less likely to fall down. This updated design reduces wear on moving parts during use, effectively extending the product's life.
