Bold red letters on a black background, and a greeting that sounds exactly like the second round of eggnog: "Merry Stoned I'm Christmas." This Add-A-Joint card has a slot for a pre-roll and comes with a matchbook and a matching envelope. It measures 4.25 x 5.5 inches and is blank inside, so the message is all yours. Pre-rolls are sold separately. Pick one up at the counter, slide it into the slot, and the card doubles as a stocking stuffer.
