In January 2024 I ran a Kickstarter campaign to create 100 limited edition decks of the Smallest Deck of Playing Cards in the World and they sold out in a couple of hours.

The cards measure 5.0 x 3.6 mm and have now been officially verified by Guinness World Records.

There may well be some sort of V2.0 of these so sign up to the newsletter if you want to be first to hear about them.
