Greeting Cards with a Conscience (and a Whole Lot of Charm) These beautifully illustrated greeting cards are 13.5cm x 13.5cm (or a neat 155mm when packaged if you choose the biodegradable cello bag option). They’re printed on slight textured 280gsm recycled card with a matte finish and paired with a biodegradable kraft envelope — totally plastic-free, just how we like it! Cards are sent loose as standard, but if you prefer them wrapped, the bio-cello bag option is available too. The inside? Blank — ready for your customers to add their own thoughtful words, silly jokes, or heartfelt scribbles. I'm a one woman show. I design, print, trim and package all orders from my home studio.
