Review on 🔆 Versatile Blank Magnet Sheets: 24-Inches Wide, .30mil Flexible, Printable, DIY Craft Projects. Safe on Vehicles, Easy to Cut - 10 Ft. Roll. Made in America! by Dwayne Quarles

I ordered a roll of magnetic sheets to create a custom sized 24x24 vent cover. I was concerned that the magnet might be too weak to stick to the ceiling opening. I WAS WRONG. The magnetic backing is very strong and sticks very well to the metal air vent frame. The thickness of the leaves was very impressive. I was afraid of being disappointed. I was very pleasantly surprised by this product. He was easy to work with and just what I needed.
