Isograph Technical Drawing Pen, 0.20 mm

I have purchased and used just about every brand of this type of drawing pen for over 50 years. I bought 3 thicknesses of this pen, and all are the perfect thicknesses---after being compared to all the "thickness" examples available for comparison. Most pens of this type will dry out as soon as a day without use, but these pens have lasted over 10 days just sitting on my desk. Extremely happy with this purchase, and I will certainly order more if I want additional drawing widths.

If you take good care of this pen, it will preform like a pro. Lines are beautiful, but if you aren’t familiar with these types of pens you may want to spend some time getting to know how they work, how to refill them and how most of all how to properly clean them.

Great product and easy to use. now I need black

It is difficult to express how superior the Rotring pens are to the Koh-I-Noor version, in my opinion. I gave up on tech pens years ago, after spending far too much money for a poor student on pens that clogged on days of the week ending in "day". It seemed at times just looking at them made them clog.(Edit) I am updating this to say that it is imperative that you use Rotring's ink in these pens, although I suppose the Koh-i-noor tech pen ink would work as well. Don't Use Dr. Martin's in these. I have 4 Rotring Isographs: .2, .3, .35 and .4. They are, in a word, superb. I generally draw on cotton paper, and the feel is superior to the other product. I have tried Faber Castell and Alvin as well. Alvin was superb, but extremely scarce. Faber Castell...don;t waste your money. The Rotring Isograph is what a technical pen is supposed to be. In essesnce, Koh-I-Noor, F, Castell= Ford Pinto. Rotring=Porsche 911. And they COST LESS.

This pen is great. I really like it and highly recommend it for anyone wanting to create thin lines. I use it with white ink to create facets on gemstones. It's perfect. I only gave it 4 stars instead of 5 because it's a little tricky to get used to. Since the tip is so fine, it clogs a lot and the ink won't flow. The trick is to barely touch the paper with it. Don't put a lot of pressure on it. Also make sure to clean the tip often by soak it in warm water and alcohol. I hopes this helps.

It works great

classic. i went several years without a rotring and decided to get some. (i lost mine in a move) its been to long and its nice to be home. if u love to draw with fine line ink pens dont hesitate. these pens last forever. dont waste your time and money on disposable art pens. this is the one to buy. side note: i also have the 2.0 and im not sure if there is any real difference.between the line size. if there is, its very subtle.

Gotta tell you I think this is way way way over priced crap. Got this and it stopped flowing ink after 1 use. I followed instructions and it’s as dry as Phoenix. My $9 fountain pen writes like butter. Very disappointed. I would NOT recommend. I can’t take any blame, used it right out of the box as supplied for $30 and junk.
