Stop Worrying About Your Magnet Flying Off — Focus on Your Route. This professional 3-pack includes 2 large 11.5"x6" and 1 small 9"x4" heavy-duty reflective delivery magnets engineered with thick, premium magnetic material that holds firmly at highway speeds — solving the #1 complaint across every competing brand. The high-intensity reflective surface keeps you visible in daylight, at night, in rain and fog, while the oversized format ensures other drivers read your "FREQUENT STOPS" warning from a greater distance than narrow competitor strips. Removes cleanly in seconds with zero residue or paint damage — ideal for personal vehicles. Fully weatherproof: UV-resistant, waterproof, and heat-tolerant for year-round daily use. Includes a protective storage box to keep magnets flat and prevent edge curling between routes. Compatible with Amazon Flex, DoorDash, Instacart, Uber Eats, UPS, FedEx, and all gig delivery drivers. For smooth steel surfaces only — not compatible with aluminum, fiberglass, or plastic panels.
