This is the standard edition slipcase of the calendar. For the special edition slipcase please go here. You know the drill by now. The 2020 Short Story Advent Calendar is a deluxe box set of individually bound short stories from some of the best writers in North America. This year's slipcase is a thing of beauty, too, with electric-yellow lining and spot-glossed lettering. It also comes wrapped in two rubber bands to keep those booklets snug in their beds.
