The Principal nib is a modern version of the famous Principality nib, which was very popular 100 years ago and still remains popular, and expensive, when you can find one for sale.
You can double the volume of ink or paint stored in the pen by removing the reservoir and filling the body. The reservoir provides a double wall of guaranteed protection, which might be what you want, but it does reduce your carrying capacity.
