From the D&D website:
A variety of D&D brand playing cards housed inside a luxurious tuck box. Limited to just 1,802 units, this unique offering was made exclusively for Black Friday and will not come again.
The collection features an assortment of D&D playing cards, both available and out of print. The outer case was designed out of necessity as the majority of the decks offered within were from print overruns and lacked an original tuck box, to begin with. This innovative new way of offering those particular decks gives life to them once again while providing a bit of mystery and perhaps even collectibility.
The unique tuck box features a perforated window that can be removed to reveal the deck inside without cracking the seal.
