Sticker on the Back of MicroSDHC?

Hi folks, I just got a “SanDisk Ultra 32 GB MicroSDHC” (here’s what it looks like:,,) and I was wondering if anyone could tell me why the card came with a little plush sticker on the back of it.

What is its function? Is it a sign that I got a real SanDisk card, as opposed to a fake? What happens if I take it off?

I’ll upload a picture to show:

Thank you!
