The answer is Pokémon cards, of course! The Pokémon TCG: Poké Ball Tin contains:
• 3 Pokémon TCG booster packs (Each Sun & Moon Series booster pack contains 10 cards and 1 basic Energy. Each XY Series booster pack contains 10 cards.) • 1 Pokémon coin
Cards vary by pack. Packs and coin may vary by products.
