Mini pendulum with a gold finish. The pendulum itself measures about 1.25 inches long and unscrews to reveal a tiny hidden compartment. The chain is approximately 9 inches long.Compartment Size:The size of the compartment is kind of dictated by the lid, which fits inside the main chamber. So you have to fit whatever it is into the lid, and then screw it together. That section is about 3/8th of an inch wide and approximately 5/8ths of an inch deep. Small gems and crystals would fit, or small amounts of sage and herbs. Or a small scroll with a prayer or intention.
