This is part of a SEKAI NO OWARI button badge set. The three small ones (approx. 2.5cm in diameter) are goods from the ARENA TOUR 2014 "Flame and Forest Carnival - Starland Edition-", and the medium-sized blue one is a bonus button badge from a CD or something. They were displayed and stored indoors. There are no scratches or stains on the front, but the back has some cloudiness and roughness. Instant purchase is welcome. Anonymous shipping will be used.
