This is the Rising Hopper Progrise Key that comes with the DX Hiden Zero-One Driver. I am selling it because I bought the Memorial version and no longer need it. Instant purchase is welcome. Operation has been confirmed. There are scratches on the Progrise Key itself. If you purchase it at the same time as the theme song version Progrise Key I am selling, I will discount it to 770 yen. Please comment if you would like to do so. No claims and no returns, please.
