Pokemon Terastal Festival ex Japanese Booster Box

Terastal Festival ex booster packs contain double the usual amount of cards (10 instead of 5), including a guaranteed Pokemon ex. This set is known as a "High Class Pack" due to its larger packs, guaranteed hits, and secret rares. Notably, Terastal Festival also features unique reverse holo cards with a "cracked ice" layer and a background of Poke Balls.
