Letterman IV letterbox made of stainless steel in bright green The Letterman IV letterbox is a simple yet eye-catching letterbox made of high-quality materials. Both rust-free stainless steel and powder-coated steel have been used. A flap, under which the opening and lock are located, protects the post from wind and weather. The flap also contributes to the incomparably purist design. As a special extra, the Letterman has a letterbox bell. This is embedded in the green letterbox and lights up in red. This modern letterbox is also supplied with two keys and a nameplate. Please note: The LED converter available as an accessory is required to operate the bell.
