The newest iteration of these successful items will be made to be sold on consignment. They feature a 12 mm lobster clasp in a matching antique gold finish, and come with one free CR1025 battery for powering the light inside.
EDIT: After some test-marketing, I have revised the price point of these items to $18 USD each.
They are now available as a regularly stocked item.
Be sure to specify the color(s) desired when ordering. Two different styles of locket ball exist; a specific type can be ordered as supplies allow.
