Pokemon Card Abyss Eye Booster Pack M5 - JP

What's included in the Japanese Abyss Eye Booster Pack?
Official product from The Pokémon Company, factory sealed:

1 booster pack
5 cards per pack
Main setlist of 81 cards
Abyss Eye (M5) expansion pack
Abyss Eye continues the Mega Evolution era storyline that began with Mega Brave, Mega Symphonia. The set revolves around Mega Darkrai ex as the star Pokémon, with a dark visual style.

This expansion is on par with Pitch Black, which will be released in English a few months later, so opening the Japanese version is the fastest way to access the card pool before its global release.
