Terastal Festival Booster Pack Sealed Pokémon Korean (sv8a)

Korean Terastal Festival ex set (set code: sv8a), a 2025 Scarlet & Violet special set (also called Prismatic Evolutions or Festa in related releases). It centers on Terastallization, Eeveelutions, festive/prismatic themes, and includes SARs, master balls, and reverse holos. Note that Korean boxes have 10 packs with 10 cards each (higher card count than standard), so individual packs likely follow with 10 random cards. It's popular for shiny/terastal variants and Eevee family collectors.
