This classically designed pen is based on the idea of a skeleton key – used for over two thousand years. The keys were able to open a large number of doors with locks which that similar enough for the key to work. These locks were designed centuries ago, and were widely used until the early twentieth century. Many old fashioned skeleton keys were made during an era when elaborate metalwork was prized, so we’ve created a skeleton key pen clip.The finish is formulated to simulate the sophisticated sheen of time-worn metal. The authentic patina and natural darkening brings out the details of the finish and creates a unique feel with a charm all its own. It will add a sense of warmth to your to your handmade creation.
