The kind of use that you can put your locket necklace to basically depends on your needs. For instance I have seen a good number of people using their lockets to store their medications. I do not really know the kind of medications which were being stored in the lockets but for sure I have seen people pick their medications from their lockets. This at first seemed weird but I got to understand that the owners of the lockets were at liberty to do as they wished with their lockets.
I have also seen a good number of people using the lockets to store poison which they use in their hunting. Basically I have come to appreciate the fact that a person can use the locket necklace to do what he or she wants. I now know that the locket is not just needed to help in keeping the memories of our loved ones.
