DIYMAG Blank Car Magnets 24x17 inch 2-Pack — 30 mil Printable Vehicle Signs, Reusable Protective Magnets

DIYMAG Blank Car Magnets are a pair of 24 x 17 inch, 30 mil thick magnetic vehicle signs designed for easy customization, secure adhesion at road speeds, and reusable protection of painted surfaces.

These magnetic sheets give you a quick, removable way to brand, block, or personalize a vehicle without permanent adhesives. Each pack includes two white, inkjet-printable magnets with rounded corners and reinforced magnetic backing. They adhere to ferrous metal surfaces, accept a range of inks or permanent markers, and come off cleanly for temporary use or reuse across multiple vehicles.

How secure are these magnets at highway speeds?

The magnets feature a 30 mil thickness with reinforced magnet material to maintain contact with the metal surface even while driving. Rounded corners and a flexible backing help the sheet lie flat so wind lift is minimized.

• 30 mil thickness for stronger hold
• Reinforced magnetic layer reduces detachment risk
• Rounded corners help prevent peeling at edges
• Designed for clean, smooth ferrous surfaces (not aluminum/plastic)

Can I print logos or designs directly onto these magnet sheets?

Yes — the white vinyl surface accepts inkjet printing, solvent and eco-solvent inks, latex inks, and permanent markers, letting you create custom graphics or simple text. After printing, trim to shape as needed and apply for instant branding on a vehicle.

• Printable vinyl topcoat compatible with common printer inks
• Cut-to-shape for bespoke logos or decal outlines
• Works well for temporary promotions, event signage, or personal designs
• Allow inks to dry fully before applying to avoid smudging

Will these magnets damage my vehicle’s paint?

When used correctly on clean, smooth ferrous surfaces, the magnets are reusable and remove without residual adhesive. They are intended to be applied flat and removed periodically to avoid trapping dirt that might scratch the finish.

• Non-adhesive magnetic backing leaves no sticky residue
• Recommend cleaning surface prior to application
• Store flat to prevent curling and maintain adhesion
• Not suitable for non-ferrous panels like aluminum or fiberglass

How versatile are these signs for different uses?

The magnets serve multiple roles: temporary vehicle advertising, covering an existing logo, protecting a panel during transport, or acting as a reusable decal. Their flexibility and printable face make them suitable for both professional and personal projects.

• Two magnets per pack for driver and passenger sides or multiple vehicles
• Can be trimmed into smaller shapes or layered for effect
• Useful for contractors, small businesses, event staff, and hobbyists
• Reusable across seasonal campaigns or vehicle swaps

Who is this for? DIYMAG's 24 x 17 inch blank car magnets are aimed at small-business owners, mobile professionals, event teams, and anyone who needs a removable, printable sign solution for ferrous vehicle panels. If you want temporary branding that prints crisply, protects paint when applied properly, and can be reused across multiple vehicles, this two-pack offers a practical, low-cost option.
