If you've selected a colour of leather for your custom book cover but feel the need to make it 'extra' then a splash of gold, emerald or sapphire will certainly do the trick.
The Metallic Touch is a random spatter of gold paint added across the leather by hand. It's pattern is unpredictable, so there's no telling how the leather will look when it's fully build into a book cover. How's that for unique?
You can add any of the Metallic Touches to your cart if you've added a custom book cover or notebook to your cart as well. This can be an engraved or a fully painted version. In the case of the fully painted version, the Touch will be applied before the hand painted details come in. Cannot be applied to already made items (we need to apply the Touch before we start engraving).
