A review for Custom magnets by Meghan Tutolo.
As they claim, the magnets seem pretty strong and durable. Only time will tell. But I must admit, though I knew they'd be on the thin side, they are much thinner than I expected. Also, the corners ding up and bend pretty easily. It's super noticeable with the black background of my design.
I notice this also sort of makes the corner edge stick up when on the car. Because I'm selling them, this sort of makes more of a difference. I'm just selling them for less.
