Combining the tactility of an injection moulded elastomer body and a machined solid wooden base. Convoy is designed purely to complement the iPhone. The elastic body provides users with a comfortable grip and a highly tactile button press, while the wooden base is intended to carry a spare SIM card and the iPhone SIM pin ejector. Each of the wood bases is hand polished and made from a unique piece of wood – please allow variations in grain and tone. It will withhold structure within reason of wood as a material. Black Walnut is rated highly regarding durability and decay resistance. Sustainably harvested in Ohio, Midwest US.
