In Marla's words: "Our locks could not exist without both the hand and the machine. By this I mean the hands of our talented jewelers and engravers and the modern technology that has allowed us to create these tools made of precious metals with great precision. Our Hand Engraved locks are the highest expression of this. We give master hand engravers our Large Heart Locks and let them engrave them at their discretion. No two are alike. We chose this size specifically to allow a generous surface area for the artistry to unfold."
