When Hong Kong’s first official Pokemon Store, Pokemon Hub, opens on December 15, it will kick off with a good start by doing its part for the environment.

Customers visiting Pokemon Hub will be able to purchase special reusable Poke Ball bags that let you carry anything from plushies to TCG cards. Not using the bag anytime soon? You can fold it into a square shaped Poke Ball. What a brilliant idea!

There isn’t a price tag announced for the reusable bags yet. The Pokemon Hub teases more designs will follow in the future.
