In the first opening sequence of Cardcaptor Sakura, towards the end she is shown carrying some sort of object which has written on it "SAKURA" in blue.
It seems to be tied to her hand or something. Apart from the letters, it seems to be orange, though it may have been intended to be transparent. I think I've seen the same thing in at least one of the episodes, though I don't remember which and I don't remember it being explained there. I really can't tell what it's supposed to be.
What is the object in Sakura's left hand in the above image?
