Based in Vancouver B.C., Cardideology believes in the tradition and lovely sentiment of giving and receiving greeting cards - even in the world of technology. While their cards make lasting impressions, they make minimal impact to the environment. Each is sustainably made using paper that is FSC Certfied by the Rainforest Alliance and e-Green Certified. This means they are 100% manufactured with wind power and sustainable materials. Plus the clear sleeves are completely compostable.
