the Bobi letterbox is a very spacious and watertight letterbox, suitable for both home and business use. 
The model is always equipped with a spacious stainless steel insert valve, which can be adjusted entirely according to need by means of an easy-to-operate screw bolt on the inside of the valve. 
From completely closed (useful around the turn of the year) to a maximum opening of 8 cm. This makes the Bobi letterbox also suitable for receiving small packages. 
The unique rubber seals around the letterbox door provide maximum protection against water in the letterbox.
