Pokémon Japanese: Mega Symphonia Booster Box (M1S) is a sealed box from Japan’s MEGA-era release that brings Mega Evolutions back to the Pokémon TCG, with the set’s spotlight chase centered on Mega Gardevoir ex. It’s a fast, rip-friendly format that’s great for set building, trading, and hunting high-rarity artwork cards in Japanese print.
Box configuration:
30 packs per box
5 cards per pack (150 cards total)
What you’re chasing:
Mega Evolution Pokémon ex headliners, led by Mega Gardevoir ex
High-rarity upgrades (full-art style cards and top-tier chase pulls) that Japanese sets are known for
A clean parallel-and-rarity ladder that makes full-box rips feel active
Why collectors buy this sealed box:
Short packs make opening quick and easy to sort
Strong display value for Japanese Pokémon trading cards, especially if you collect MEGA-era themes
Pairs naturally with the companion release Mega Brave, giving you a broader MEGA chase lane across the two sets
