Book AutowerksThe print quality is great. The magnetic backing is thinner than most magnets of this type, but they still stick well to the fridge.

Frequently asked questions
FAQs
Don't let their size fool you! Our custom magnets are thin, high-energy magnets with a pull of 65 pounds per square foot. This means one square foot of material can hold up to 65 pounds. That's stronger than most flexible custom magnets on the market today.
In practical terms, this means:
They'll easily hold three sheets of standard 8.5"x 11" paper on a fridge, so you can turn your kid's art into a magnet to hold your kid's art!
They'll stay stuck to cars driving at highway speeds, so you can boast that "my other car is a bicycle" wherever you go.

Our custom magnets are about 0.38mm, or 15 mils, thick. For reference, this is about the same thickness as our vinyl stickers with the backing on. Mil is a unit of measurement equal to one-thousandth of an inch and is commonly used for measuring products like magnets and stickers.
It's important to keep in mind that thicker magnets do not necessarily mean stronger magnets. In fact, many of our competitors use magnets that are 20 to 30 mils but have weaker magnetic pull. The strength of a magnet depends more on the quality of the raw materials and the manufacturing process than on thickness alone.

Our magnets have a 65-pound per square foot pull strength, allowing them to securely adhere to cars and stay put at highway speeds. Their durable material resists rain, snow, and sleet. Made from 15mil (0.38mm) material, they offer a stronger hold, better adhesion, and a more aerodynamic design than the 20mil (0.5mm) or 30mil (0.726mm) magnets sold by many competitors.
Flexible magnets generally won't damage car paint if used properly, but we recommend the following best practices to keep your car and your magnet in good shape.
- Apply to a clean, flat metal surface with no dents or deep curves.
- Remove and reposition regularly (weekly is ideal). Be sure to remove any trapped dirt or debris and clean any moisture that might have collected under the magnet.
- Store flat when not in use to prevent warping.
- Avoid applying over decals or vinyl wraps.
- Avoid prolonged exposure to extreme heat (such as direct sun), which may compromise the magnet's backing.
