RotringIsograph Technical Drawing Pen, 0.35 mm

Normally not a big fan of rotring designs: I've had many issues with their other products. However, the isographs work really well. Pen point is very smooth and consistent, cap seals very well (I've left a pen for 1.5 months without use, and it still writes immediately afterward), and it holds a good amount of ink (can use pigmented fountain pen ink, such as deAtramentis or Platinum Carbon Black). I've stocked up on these, since technical pens are going out of production.

I am collecting two things, pens and watches.This is a novelty item and reminding me of my set from when I was in high school. Few years ago, I had a hard time trying to buy this pen on Amazon and I can only find them from a bidding site. I was overjoyed that I can buy this pen now on Amazon.Rotring makes great quality pens and I owned a variety of the technical drawing pens and also their fountain pens. All of them are working to the standard that I am expecting out of Rotring.Note: If you are not used to writing/using technical drawing pens, then this pen is not your daily use pen. If you press a little too hard, you will ruin the small needle and making it unusable or worse bending the needle.

0.35 radiograph arrived in original sealed packaging in perfect condition. This is one reliable Rotring seller.

Good.

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.

Not worth the price. I have other Rotring pens, and this is not up to their standards. It will not only dry out real fast, even with the cap on and positioned horizontally, but the nib gets clogged. Trying to clean it only removes the nib in its entirety. Complete waste of money.

I really enjoy the Rotring pens and the reusable aspects, for office use and academic work the isograph, art pen, and mechanical pencil are performing great. Additionally, it does save significant expenses in the longer run, I don't need to buy a new pen/writing tools every couple of weeks and there is some satisfaction with the feel of the ink spread on the paper for writing, doing calculations, and technical drawings.

They are better made, ink flows right away and I think they have a lifetime guarantee. Someone correct me if I'm wrong about the latter. The best deal is on Amazon - the College Set .20, .30, .50. Incredible packaging, comes with a mechanical pencil, leads, ink and a few other cool doodads. Check the price on Amazon. I got the College Set for around $46 which is roughly $15 a pen. You can't beat that anywhere.
