Panty Liner

I got to Eryn's school festival yesterday, where I was scheduled to run the ring toss, and after I entered the gymnasium, Pooteewheet was flashing one of these at me from her pocket and pointed out that they could be won for scoring a successful ring toss. All I could think is, "Why would they give away panty liners to children?" Followed closely by, "What sort of idiot makes and/or wears a psychedelic panty liner?"

Turns out, it's a book mark. I should have known. Although if it WAS a pantyliner, perhaps this was the intended use.
