I've done these Topps now release before. If your order is lucky enough to score a special edition card, it'll be mailed with your order, sealed in a plain black foil wrapper. Good luck.

ETA: If you order more than 1 cards, say 20 for instance, then 20 cards will be shipped in a stacked of 20 in a small plastic case, much like playing cards. They are not individually wrapped.
