This fountain pen incorporates the traditional piston-loading mechanism with the exclusive Aurora reservoir. When the ink runs out, simply turn the base counterclockwise and the hidden reservoir will provide ink for approximately one more sheet of writing. The base of the pen can be left rotated as a reminder not to forget to refill the fountain pen.
I found Iguana really friendly, helpful and efficient to both buy the pen and when I had a query - very quick to respond. The pen is gorgeous and I’m now using it every day.
