Peko-chan's Not-for-Sale Can Badges - Complete 12-Month Series + Antarctic Peko-chan (slightly larger size) It was difficult to collect them all, but I've gathered the entire seasonal series. However, they are quite old, so I don't remember exactly when they were released. I wore the Antarctic Peko-chan badge once, but I don't remember using the others. These items have been stored for a long time, so they may have scratches or other imperfections. Please examine the images and refrain from purchasing if you are overly concerned about their condition. I will not sell them individually. The size is approximately 3 cm (diameter), and the Antarctic one is about 4 cm.
