How to use: Open the blister pack and take out the Pokémon cards. You can start a battle with your friends right away. Mix and match different Pokémon to create your own powerful deck. Note: Keep the cards away from water and sharp objects to prevent damage. If there are any damaged cards, contact the seller for a replacement. Maintenance: Store the cards in a cool, dry place. You can use card sleeves to protect them from scratches and dirt. This will keep your cards in good condition for a long time.
