Car Door Magnets - 300 x 420mm

Professional Magnetic Vehicle Signs for Business

Make your vehicle stand out with professionally printed magnetic signage in a larger 300 x 420mm format. Custom car door magnets provide an effective way to display your business name, logo, services and contact details while you're on the road.

Ideal for tradespeople, contractors, mobile businesses and service providers, these car door magnets offer flexible vehicle branding without the commitment of permanent graphics. Apply them when you want to promote your business and remove them when they are not needed.

Our 300 x 420mm car magnets provide generous space for clear branding and easy-to-read business information. The larger format is ideal for displaying your logo, phone number, website, services or other important details prominently on your vehicle.

Each magnet is made from commercial-grade flexible magnetic material and is 1.2mm thick, providing a durable signage solution for suitable metal vehicle surfaces. The full magnetic backing allows the sign to sit securely on the vehicle while remaining easy to handle and store.

These magnetic vehicle signs can be customised with your business branding, colours, graphics and contact information to create professional vehicle signage that helps customers recognise your business wherever you travel.

Full-Colour Printing with a Gloss Finish

Your design is produced using high-definition CMYK digital printing for vibrant colours, sharp details and clear graphics. The glossy finish gives your magnetic car signs a clean and professional appearance.

The magnets are printed on a glossy substrate and do not require additional lamination. This makes them a practical choice for businesses looking for high-quality custom car magnets with a professional printed finish.

Whether you want to showcase your logo, promote your services or provide customers with an easy way to contact you, these car door magnets offer a practical way to support your vehicle branding.

Flexible Vehicle Advertising

Use your 300 x 420mm car magnets to display:

• Business names and logos
• Phone numbers and websites
• Services and contact details
