Pokémon EX Delta Species Booster Box — Sealed, English (2005)

EX Delta Species is one of the most celebrated sets of the entire EX era, set in the Holon Research Tower — a research station where scientists study Mew and newly altered Pokémon after an electromagnetic experiment goes wrong. The narrative result is the Delta Species: creatures whose type differs from their original form, marked by the δ symbol between name and HP and by a double-helix border, one of the most original mechanics in the history of the TCG.

The set carries three of the era's iconic Gold Star cards — Groudon (#111), Kyogre (#112) and Metagross (#113) — alongside Rare Holo ex versions of the Eevee evolutions: Flareon ex, Jolteon ex and Vaporeon ex. More than half of the holographic cards depict highly popular Pokémon, including Latias, Latios and Rayquaza, which widens the appeal of the expansion well beyond Delta Species specialists.

This example is a sealed English booster box of 36 packs, nine cards per pack, never opened, in one of the four wrapper variants produced for the set — Flareon, Dragonite, Salamence or Metagross. Sealed EX-era boxes have become progressively harder to source, and the scarcity of intact examples is precisely what has driven their appreciation over time: a factory-sealed box preserves both the physical integrity of the product and the possibility of its most desired pulls.
