Mail from Google!

I got some mail from Google today!

Google ebooks to be exact. I thought it was just like a receipt for an ebook that I purchased from them a while ago or something. But after opening it I found that they sent me these:

I'm not sure exactly what they are supposed to be. They look like bookmarks. But from Google ebooks? Maybe that's the joke! HAHA! They are plastic-y I guess. But I'm still stoked that I got REAL mail from Google! As I'm a Google junkie basically. Google FTW!
