Source files for [citation needed] stickers, styled after the characteristic Wikipedia style.

Wikipedia typically uses sans-serif font, blue links are colored in #0645AD. While the stickersheet file contains a set of different sized stickers (dpi 720; sticker sizes: 300x40mm, 156x21mm, 100x15mm and 62x11mm) and can be ordered as a sheet, the single sticker file can be resized individually (dpi: 720; size 100x15mm).

Regarding the license: I'm not sure if CC0 is applicable at all, as the level of creation is quite low. Nevertheless, I added CC0 to make it clear that you can use and change it as you like (see license).
