These Core Medals are fun collectibles. When using them, just take them out of the box and enjoy looking at their painted details. Remember, we can't promise they'll work with the OOO Scanner from the DX Release of the OOO Driver. Store them in a dry and cool place to keep the paint from peeling. If you bought the USA release, check the translated instructions for more info. Don't drop or hit the medals hard as they're die - cast and can get damaged. For Full Payment preorders in the USA, you'll get free shipping, so sit back and wait for your set to arrive.
