Harry Potter Keychain Timeturner

I don't know much about the Harry Potter series. I do know this is a Harry Potter piece of memorabilia. The bay has several listed. One says episode 126. Really don't know if that helps but I thought I'd throw it in. This key chain has been pre-loved and it's not in perfect condition. I will clean it well before you get it. Please look at the pictures because they are an essential part of the item's description.
