A pin inspired by an analog mixer, like SONY's. This pin is modeled after a mixer for a small commercial facility that emphasizes music. Hard enamel technique (simulated cloisonné). The fastener on the back is a butterfly type. I bought it at a musical instrument store in Shibuya a long time ago and kept it carefully. Unused, new condition. Thank you for looking. #PAmixer #recordingmixer #sony #Sonysoundtech #mixer
