A million years ago (seems like) I made these for the Excalibur hotel - we used to fill them with pixie dust for the little princesses and the little wizards. It's not the smallest vial I have but sort of a medium one - measures 1.75" long - glass bottle - all pieces domestic including the celtic design - clear rubber stopper with an elegant little matted silver celtic findings adhered to the front. A usable vial - blood - magic potion - pixie dust - secret little note - use your imagination.
