Cross has made it extremely easy to check the ink level in your fountain pen! When unthreading the barrel of the pen, it twists the top of the converter, depressing the piston, and ejects the ink remaining in your pen onto the surface of your desk where you can easily gauge how much was left in the pen.
This is such a great feature I can't believe they don't advertise it on the converter's packaging!
