You can’t buy a better ink pen for technical work than a Rotring Isograph. I’ve been using them for decades. They never break, I just lose them.Reading the reviews, it seems like a lot of people have never used an actual technical ink pen. Unlike rollerball pens and pigment markers, the amount of pressure required for precise ink flow requires practice. It’s more like a fountain pen. Once mastered, you won’t find anything better.I see a lot of comments about clogging. If it stops inking, just give it a little shake. If you shake the pen you can hear the needle move. That’s by design. Shake it and ink will flow again (see video).As with all free flowing pens, it’s a good idea to have a blotter page.The most important thing to remember is to clean them. With the very small line widths, the actual needle is about the diameter of a human hair. If you let ink dry in the pen, you’ll never get it working again. There’s simply not enough room for solvent to get in.To clean them, simply wash them in the sink with warm water. No need for anything else. Take the reservoir and end cap off and run water through it until there’s no more ink coming out. It takes about 2 minutes to throughly clean it. Never try to remove the needle. It will bend when you try to put it back in. It’s very, very, very small.

I think this is the kind of pen, you either love it or you hate it. I love it, but it is not without upkeep. Occasionally I forget about it for a couple of weeks, so I just run the tip under warm water and it comes back to life.

Many rotrings come broken like mine did. The company uses cheap brottle plastic not suitable for a 40$ pen.

Great product and easy to use. now I need black
