PITT Pens and Copic Markers. This is for the new DC 52 sketch card set from Cryptozoic Entertainment and DC Comics. This is not typical card size, but an oversized 4x6 card. Since they can't put these in card packs, somebody out there will find a card that can be sent in and redeemed for one of these big'uns! I did 15 for the set, as well as 50 regular sized cards. More to come!
