[Unanswered]  Corocoro's bonus stickers

Hi guys, i've only bought one issue of corocoro (for the metal god chip). But i've been glad about another, unexpected (at least for me) bonus: a sheet with alternative stickers. Now, i'm wondering: does every issue features some of these? I'm searching for xcalius x1's decals, do you know if corocoro has ever published them?
Thank you.
