Play Mahjong Fight Club Extreme at participating stores and get original goods!! The MF earned by playing is counted for each e-amusement pass and for each campaign store. If you accumulate the required number of MF at one store, you can exchange them for goods at that store. Designed by Mahjong Fight Club's Mari Takamiya and Arisa Date. Brand new, unused, and will be sent in a bubble-wrapped envelope.
