400gsm Smooth White A3 Craft Card

£10.49

A3 (297mm x 420mm) 400gsm Smooth White FSC Certified Cardstock – The Heavyweight Champ of Paper.

If cardstock had a gym membership, this would be the one lifting the heaviest weights. Meet our A3 400gsm Smooth White FSC Certified Cardstock—a premium, planet-friendly powerhouse designed for big ideas, bold prints, and projects that refuse to be ignored. At 420mm x 297mm, it’s smooth on both sides and thick enough to double as a mini clipboard (okay, maybe not officially, but you get the idea).

Some quick printer info:

This cardstock is pretty bulky. At 400gsm, it’s not just paper—it’s a statement. Before you ask your printer to take on this absolute unit, check your machine’s max gsm capacity to avoid any unfortunate paper jams, printer tantrums, or dramatic sighs from your office equipment.

✅ Eco-Friendly & Extra Fancy – FSC Certified, so it looks good and does good for the planet. Sustainability never looked so smooth!
✅ Invitations That Wow – Weddings, milestone birthdays, or “We Finally Got a Cat” announcements—this cardstock screams premium.

✅ DIY Superstar – Greeting cards, scrapbooking, or even building a tiny fortress out of paper (we won’t judge).

It is difficult to show accurate colours or the quality and finish and weight of our paper and card on a screen. If you are unsure of its suitability for your purposes we suggest you place a small order to try.
Cards are suitable for home printing, please always check your individual printer specifications prior to attempting to print, as we cannot guarantee all printers will accommodate thicker paper/card.
