This extensive collection of Pokémon booster packs, featuring rare editions like Mega Sinfonia and Mega Dream EX, highlights the enduring popularity of the franchise within the trading card game community since its debut in the late 1990s.

Collectors often seek these specific packs due to their limited print runs and unique artwork, which can significantly enhance the value of any collection.

The pristine condition of these unopened packs, sourced from Japan, ensures their authenticity and potential for future appreciation in a market that rewards rare and well-preserved items.

Given the current bid of ¥21,000, this lot represents a competitive entry point within the context of Japan's vibrant Pokémon collecting scene.
