Direct from Pokemon Center Japan:
Rubber play mat Blastoise
The back side is made of rubber, so you can play comfortably without the mat sticking to your desk!
Now you know where to put the card!
We will update the process to access the Destined Rivals closed sale shortly. Apologies to those contacting us about trade-ins process. We do accept lists of cards (Card Name + Set List) and drop-offs, but we are currently catching up on large amount of trade in traffic. We are backlogged due to time constraints.
