First and foremost rounded corners extend the life of your magnetic signs.
We have been in the magnetic sign business for 25+ years and have found that when it comes to the corner finishing, of these particular vehicle signs, that rounding the corners adds to their longevity and overall clean appearance on the vehicle. Square corners will eventually start to dog-ear after a few years of continually peeling them off of your vehicle. Which is a necessary evil of purchasing magnetic signs as they need to be removed and cleaned from time to time to keep them looking bright and vibrant. Plus you'll want to clean any build-up behind the magnetic sign as well.
Through the years, we found that by slightly rounding the corners of our magnetic signs it greatly reduces the dog-ear effect that afflicts the square cut corner magnetic signs. For this reason alone we highly recommend that customers choose the rounded corner option too extend the life of their magnetic sign. Rounding magnetic sign corners is a simple process and costs pennies on the dollar which makes it totally worth the few extra dollars to round the corners on your magnetic sign order.
And as for the visual aesthetics of magnetic signs with rounded corners there is no questions that visually the rounded corners give magnetic signs have a a cleaner look over square corners. Rounded corners seem to blend better with all vehicle makes and models, over the standard square cut corners that tend to look a little harsh, and like mentioned above, will eventually dog-ear. When magnetic signs dog-ear they tend to look dated which ruins the overall look of your magnetic signs and once the corners are compromised it allows air to get underneath the magnetic sign which can lead to your magnetic sign possibly flying-off the vehicle someday.
