6" x 4" (102mm x 152mm) 450gsm Smooth White Card – Ultra-Heavyweight, Very Rigid & Built for Impact

This 6" x 4" 450gsm Smooth White Card is a serious step up in thickness and rigidity. Substantially heavier than standard heavyweight card, it’s designed for projects that need maximum presence, durability and a bold, professional feel.

With a smooth matte finish on both sides, this plain white card delivers sharp prints and confident writing, while its rigidity helps it stand up to handling and display. Ideal for statement greeting cards, premium invitations, postcards, menus and high-impact stationery where quality needs to be obvious.

Printing on 450gsm Card (Important)

This 450gsm card is suitable for inkjet, laser, digital and offset printing, but it is very thick. Many standard home printers will not support this weight. If your printer is rated for heavy card stock, use manual feed and print one sheet at a time. We strongly recommend testing with a small quantity first.
