As you can see, they also have a phone strap with the band's logo and shape of this particular cymbal. There will be a special event at Kanda Zippal Hall on 3/13(doors open at 18:00, and the event starts at 18:30). In order to attend this event, the phone strap or cymbal must be purchased(the cymbal costs 39,800, phone strap costs 2000) beforehand. The person who preorders either will receive an invitation to the event. The event involves a talk and autograph session.
