AzReference 24" x 12" Car Door Magnets 4-Pack — 47-mil Blank Printable Vehicle Signs, Rounded Corners

These AzReference 24" x 12" blank car door magnets are reusable, printable vehicle signs that protect paint and create easy custom branding or messaging.

Lightweight yet durable, this four-pack of 24" x 12" magnetic sheets gives you large-format space for business logos, promotions, or temporary messages while also providing a soft barrier between doors and accidental scrapes. The 47-mil thickness balances flexibility and holding power so the magnets stay secure at moderate speeds and lay flat against metal surfaces. Rounded corners reduce peeling and wear, and the white printable face works with wide ink and marker options to make them versatile for both home and commercial use.

How do these magnets hold up on a vehicle while driving?

Each sheet uses a magnetic backing sized to cover a standard car door panel and a 47-mil thickness that improves contact with metal surfaces. The rounded corners reduce lift at the edges, helping the magnet maintain adhesion during normal driving conditions.

• 47-mil magnetic material for a stronger surface grip
• Rounded corners to prevent edge lifting at speed
• Full 24" x 12" coverage for secure placement on most doors
• Pack of four gives you spares or multiple-vehicle coverage

Can I print a custom design on these magnets or use markers?

The glossy white face works with a wide range of printing and marking methods so you can personalize each magnet. They accept solvent, eco-solvent, UV and latex inks, as well as permanent and dry-erase markers for temporary notes or quick changes.

• Compatible with inkjet and large-format printers using common inks
• Write-on, wipe-off capability with dry-erase markers for reuse
• Permanent marker or printed graphics for long-term signage
• Easy to trim with scissors for custom shapes or smaller signs

Will these magnets damage my car’s paint or leave residue?

When used properly—clean, dry metal surfaces and removed periodically—these magnets are designed to be gentle on paint and finish. The soft magnetic material acts as a physical buffer, helping reduce the chance of scratches from incidental contact while remaining removable without adhesive residue.

• No adhesives—removes cleanly from painted metal when lifted
• Adds a buffer layer that helps prevent dings and scratches
• Store flat when not in use to retain shape and adhesion
• Wipe both car surface and magnet before reapplying for best results

How can I use these beyond car advertising?

These blank magnetic sheets are multipurpose: create temporary signage for trailers and vans, make reusable chore boards, protect surfaces from pet scratches, or craft classroom and office visual aids. Their write-and-erase surface and printable front open up many creative or practical applications.

• Temporary business promotion or directional signs for events
• Reusable task boards and calendars when used with dry-erase markers
• Protective layers between garage doors, neighbors, or pets
• Custom cutouts for displays, crafts, and on-site branding needs

Who is this for? Small-business owners, mobile professionals, DIY advertisers, event coordinators, teachers, and homeowners who want a flexible, removable signage solution will find this AzReference four-pack useful. If you need a large, printable magnetic surface that balances durability with easy application and removal, these 24" x 12" sheets offer a practical and cost-effective option for vehicles, venues, and temporary displays.
