Our first new mechanism lock. It's both useful and beautiful which is pure magic when that happens. This lock we will make exclusively in 18K yellow rose and white gold. You will find 4 tiny diamonds hidden in the recesses of this lock. Why does it have this name? In the movie Doctor Doolittle the Pushmi-pullyu was an animal with 2 heads and one body so they could both talk and eat at the same time. In the movie it claimed to the good doctor that its great-grandfather was the last unicorn. This lock can do so many many things--perfect on a bracelet, on a necklace, can attach to other locks.. to your charms... so many things to do with it.
