Printing Tip:
350gsm is substantial and may not be compatible with all printers. Check your printer’s specs to ensure it can handle heavyweight stock.

• Hand-lettering and calligraphy — create bespoke, one-of-a-kind pieces.

• Stamping, embossing, and die-cutting — for cards that look and feel luxurious.

• Framed art prints and keepsakes — substantial enough to hang or display.

• Packaging inserts and promotional tags — thick enough to stand on their own.

• Pro-grade greeting cards — ideal for card producers looking for a premium finish.

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.
