The section has a slight centre dip, providing a good finger grip. The cap is single threaded and can be removed within 2 turns. There is a step of around 1 mm between the cap and the barrel. The pen uses a bock nib (250 or #6) and is shown here with a steel nib (f), which you may change on request for any bock nibs, at no further cost (save for the precious metal nibs :-).
The final image above shows the various options of pen cases available at no further cost - the wood cases are turned to fit the pen, whilst the black box is pretty standard. The wooden cases have a friction fit cap, and can be turned from most hardwoods. The image shows examples of cases in walnut (darker) and olive ash (smaller), but other woods such as ash, beech or oak could be used. Finally the pen is supplied with an ink convertor, an international ink cartridge and a roll stop which will be turned from a matching or contrasting acrylic or wood.
