Santa Christmas Letters

So i just got the ide of a a type of a Santa Letter that we would be able to write and maybe send from idk Pillbox. And you could send it through a Elfs or Santas mail box. I think that everyone could get 2 letters to end during December and after new year we open them and have like a book where you can go through them and see if you got a Present or Coal!

Its something small but i could just cheer up most people i think.
