Special Edition Brick CONTAINING 12 MAILCHIMP DECKS
In celebration of this collaboration: a special edition brick box containing 12 decks is available. Like the deck itself, the box has been designed from the inside, out. With red foil on blue stock, or black foil on black stock - the brick acts not only as a beautiful container, but also protects the cards within.
