These are MYSTERY BLIND BAGS. There are 15 designs, 2 of them being fandom crossovers.
Each blind bag won't include duplicates, however if you order more than one blind bag I cannot guarantee you won't get duplicates as they've been packed and sealed before the launch.
3 different bag sizes; 1 pin, 3 pins and 5 pins.
Each pin is 25mm wide/tall.
