The "Dim Card" series is an interlocking item that expands the play of "Vital Bracelet".
By linking the "Dim Card" to the " Vital Bracelet Digital Monster", you can unlock new areas and expand the types of Digimon that can be nurtured.
The second release will be called DIM Card Set Volcanic Beat and Blizzard Fang, which releases in April. These feature Lavorvomon and Bulcomon from Digimon Links.
