I've forgotten the magazine title, but these are bonus stickers from the heyday of Urahara-kei brands. As you can see from the photo, they've been used in places. Please refer to the standard-sized pen in the picture for the size. These stickers are almost 30 years old. For those who were looking for these, or collectors, please consider them!
