Pika Pika GeGeGe.
This is a card set of 50 regular and 9 Sparkly (ピカピカ pika pika) stickers that came out last year. You got 10 in a pack and I have several doubles but as you can see, I'm 3 short of a full set! (I'm referring to the stickers, not my mind.)
I apologize if you sat through that. Really annoying, eh?
