Silvery Mad Hatter's Hat Charm

So, the Mad Hatter asked Alice, "Why is a raven like a writing-desk?" And of course, there was no answer, or is there? Or, were they just wasting time? Can time be wasted? Or, of course, of course...

Oh, my, oh, well, perhaps you'd better just put this charm on your charm bracelet and just think about what the Dormouse said.

Each silvery little hat charm measures 1/2 inch high including the loop and 3/8 inch wide.
