After the release of Halo 4, these are highly sought out figures which will inevitably become collectibles. Mega Brands has ceased production since the new series 5, 6 and 7 have been released. This series has the most demanded figure from any halo mega brands series, Cortana. Based on research cited from various sources online, the true probability of getting the ultra rare cortana is 1 in 48 packs. I personally have opened 2 cases myself in my storefront and have accounts on 2 individuals getting cortanas. I do not make any guarantees that you will receive a Cortana, but I guarantee that these cases are sealed, untampered and directly from the manufacturer.
