This bronze "Houdini Heart" locket comes with a tiny chain and lock (with a tiny heart on it). The lock is opened by gently pulling up on the U-bar while keeping a thumbnail on the upper edge of the lock to keep it in place. The U-bar is spring loaded. The locket may also be made in all silver, or in silver with a bronze latch. This locket is in development. Stay tuned for this listing to be updated with more photographs. Please send me a message if you have any questions! You may certainly pre-order this locket if you wish. But, at this time, I am not sure when I will be able to ship this one to you!
