This is a BanG Dream! (Bandori) Poppin'Party postcard. It was likely won in a social media campaign held over 10 years ago, and is an A prize postcard from Poppin'Party. I believe the number of winners was around 50,000, and it is a non-sale item. Although it's a prize I received over 10 years ago, it is new and unused, so please rest assured. I will package it to prevent it from getting wet or damaged, and ship it via Takkyubin Compact. November 30th: Price reduced. 2500 yen → 2400 yen. December 21st: Price reduced. 1800 yen → 1700 yen. December 29th: Price reduced. 1700 yen → 1600 yen. #BanG Dream #Poppin'Party #NotForSale #Prize #Postcard
