• Hand-lettering and calligraphy — add that personal, professional touch.

• Stamping, embossing, and die-cutting — perfect for textured finishes and custom shapes.

• Art prints and framed keepsakes — sturdy enough to hang on the wall.

• Packaging inserts, product tags, and promotional pieces — thick and substantial.

• Pro-grade greeting cards — ideal for card producers looking to create a premium range.

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.
