This is a leaflet that was distributed in limited quantities at select stores in North America before the release of Digimon Card Game (around 2020) as a test run. It is an unopened item and is in relatively good condition. You can find more details by searching for "Promotion Pack Ver 0.0 Special Edition". It includes parallel cards of Agumon, Gabumon, Gomamon, Piyomon, Patamon, and Tailmon. I believe this is a rare item that is not available in Japan. #DigiOverseas
