What are the International Days collectible cards?

The International Days of (...) highlight worldwide causes, remembrances and people across the year. We believe the International Days cards are an excellent way to raise awareness around global challenges and hopefully drive attention & funds to lesser-known issues and communities. We look forward to you joining us in this adventure! Each Card also gives access to the International Days classified according to 170+ keywords and the 17 Sustainable Development Goals, perfect if you create content professionally.

Each card is unique

We only issue one single card per International Day for you to collect. There are 501 cards for 2021 at 0.05 ETH apiece.


The cards are NFTs

Non-fungible tokens (NFTs) can be bought with cryptocurrencies. The cards will be available on the OpenSea marketplace.
