The High-Class Pack MEGA Dream ex series, released as part of the ongoing Pokémon Trading Card Game saga, captures significant nostalgia for fans of the franchise, which has remained a dominant presence in Japanese pop culture since the '90s.

The sealed nature of this complete set of 12 boxes adds to its rarity, as collectors often seek out unopened packaging to maintain the integrity and potential value of the cards inside.

Given that these packs were sourced directly from a convenience store in Japan, they benefit from the authenticity and condition standard expected by discerning collectors.

As Pokémon continues to experience robust interest, especially for high-class releases, this set sits at an appealing price point for both dedicated fans and investment-minded collectors.
