The locket can either be a necklace or bracelet & come in different shapes. They have glass on both sides. It can open up so that you can put the charms of your choice inside. It has magnets around the inner opening so that it will hold shut. These can be personalized with whatever charms you want to put in them. They're really cute. The charms are very small & come in almost any style you can imagine. The high end jewelry of the same type are called Origami Owls. These are like the generic version. TY!
