Cheeky Geek Time Turner Necklace

This is an unofficial item inspired by the series, not official merchandise endorsed by the author in any way. I haven't read the series myself, but I'm told the text is pretty accurate to the Time Turner in the books and movies.  

It is important to note that the hourglass part is not a functioning hourglass.  The sand flows freely back and forth between the two bulbs, but the narrow section isn't small enough to restrict the flow.  In short, you can't use it to tell time. It's cute, though!
