Rapidograph pens have to be one of the best inventions of all times, but can be cranky and stubborn if not maintained. This kit is great to keep the nibs clean and working day in and day out. The pressure bulb is a perfect fit to thread the nibs and pen bodies in for a gentle, effective cleaning. The Rapido-Eze cleans away deposits of ink that can gum up the works without harming the pens. Clean difficult ones in a small ultrasonic with Rapido-Eze first and finish off with the pressure bulb. Kit even has a nib wrench.

I've been a graphic artist for decades. Kohinoor rapidograph is the pen of choice for me throughout my whole life. This cleaning system is simple and effective and gets the job done. And that is what you want, right?
