In the case of unopened items and bundles, while you cant transfer them to Pokmon TCG Live, you will receive an amount of crystals - the apps in-game currency - based on the number of unopened products (not including specific unopened items, such as reward chests, avatar collection boxes and certain booster packs and theme decks): 1 to 9: 500 crystals 10 to 24: 1,100 crystals 25 to 49: 2,250 crystals 50 to 124: 4,700 crystals 125 or more: 12,400 crystals
