rOtring 1903394 Isograph Technical Drawing Pen, 0.1 mm

The only other pen that comes close to what this does is a Pigma Micron 005, and that pen can wear down to nothing in one drawing. And then you have to buy another Pigma. This rOtring Isograph 0.1 is perfect. The line quality is superb. It's very thin and fine and the flow never stops. You can hold it normally too. You don't have to hold this one vertically. You can tilt it just like a pencil and it flows fine. It is a bit scratchy...but that's inevitable given how thin the line is. Use good paper and this is a non-issue. I like that the pen lasts basically forever. No more throwing pens away when the nib wears down. I've had mine full of ink for a month. There is a rubber gasket built into the cap that keeps the ink wet. You don't have to clean them after every use. Because I've heard that this thinnest one can dry out if ignored for a while, I try to 'take it for a walk' every day. Dogs need to be walked, and I suspect this pen needs to have some ink moving in it every day. I might just be paranoid...but better safe than sorry. I basically just doodle. I can 'exercise' all 6 of my rOtrings in under two minutes. I have a 0.1, 0.2, 0.3, 0.5 and 0.8. I find that the 0.1 and 0.2 are so thin as to be basically the same. The 0.8 is so fat I don't really like it. The 0.5 lays down enough ink that the 0.8 is not needed. I did put rOtring white in the 0.5 and 0.8 but it flows brokenly unless you draw really slowly, so I use Gellyroll pens (white) instead. I did clean them a couple times when switching between white and black ink, and once when I was away from my pens for a month. I have not yet completely taken them apart (don't want to bend the wires)...but I like that you can if needed. I just soak them in water until the ink dilutes to nothing. It's possible that a high end fountain pen might have enough variable line width to match these rOtrings, but I can't afford to spend $200 on a gold tipped fountain pen. For now I love these rOtrings. For more of my pen work, search for: markhwebster

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 love the Isograph pens and have owned many of them. I've also owned many Koh-I-Noor Rapidograph pens over many years and ultimately gave up on them, finding that they're much more prone to problems with jamming and becoming unusable, even with vigorous cleaning, which has never been an issue with the Rotring Isographs. However, if you're not used to technical pens, you do need to be aware of a few things: First, don't buy an expensive technical pen unless you're going to use it regularly. These barrels are fine and ink will dry up if you let the pen sit without being used for very long. If you're only occasionally in the mood to draw or write, you're going to get frustrated with your expensive technical pens that will have dried up during your absence. Secondly, the finer the point, the more fragile the barrel at the tip. Unfortunately, I had to give up on using this particular .1mm pen, whose tip broke the first time I used it. It requires a delicate pressure to use, which can be a battle given that you need the ink to flow. That also depends on the paper you're using, which brings me to the last point: Your choice of paper is crucial. Normal drawing paper or anything with a rougher texture tends to create problems with these very fine points digging into the paper and interfering with moving the pen. The more smooth the paper surface, the easier these pens work. Hyper-smooth synthetic paper like the Yupo is terrific (although it's very expensive and smearing is problematic, as the ink takes longer to dry); your everyday drawing paper or paper journal, not so much. If you like the Moleskins, the sketchbooks with the thicker 111lb paper work pretty well, at least with points .25mm or thicker, but the thinner papers are typically unsuitable, as the pen point is constantly getting stuck in the paper.

These pens are very difficult to find especially in individual sizes. I have been experimenting with many types of pens for art projects(prisma, Pitt, copic, micron etc also available at Amazon) and Rotring makes a quality pen. I did some difficulty getting the pens to flow initially but once you get them started they work well especially for detailed ink designs. These pens have a cartridge so you need to purchase ink to keep the cartridge filled. They will last longer than the throwaway pens. The tips on these pens can be fragile so you need to be careful when cleaning them and taking them apart. I have read that some artists use jewelry cleaning machines to help them clean their pens. When filling the cartridge for the first time, fill away from your art project and have paper towels nearby. My first try at filling the cartridge I really made a mess. Ink does wash off well in comparison to the ink used by stampers. I would recommend this item for those who are experienced with using pens to create art work.

It is a writing instrument that I've already used for years. If properly taken care it lasts forever. I broke mine because I dropped it on the floor. Unfortunately for me it is quite difficult to find it since nobody draw by hand anymore. So this time Amazon save me!

I use Phil martin India ink - I think it’s supposed to be for 0.13 and up…but so far it’s been working pretty well with very few instances of ink flow stoppage.

This pen was recommended by an artist on YouTube so I figured I’d give it a try since I wanted to make the switch to a refillable pen. I’m so happy I did. I love it. You have to be mindful that you write with the pen in a more vertical position and not press too hard at all. I didn’t have an issue since this is my natural pen hold, but I can understand why others might have difficulty getting the hang of it. If you’re looking for a fine liner that will last longer than disposable ones, I’d recommend this one.

This was good for 2 years but now it started leaking. When I write with it, the ink leaks out no matter what I do. What can I do about this?

Produto chegou atrasado, amassado e com a ponta da caneta torta e a rosca quebrada! Para uma caneta desse valor, o cuidado com o produto foi péssimo. Demorou mais de um mês para chegar e ainda chegou danificada e vou ter que aguardar mais sl quanto tempo para devolver ou trocar.

Old but not used and original product

Ich musste einfach diesen Stift testen und habe mir inzwischen ein Set zugelegt. Mit ein wenig Übung, habe ich den Dreh raus und kann damit sehr gut umgehen. Ich nutze ihn zum zeichnen von Dot- und Lineart und muss nicht mehr 100te Fineliner kaufen, weil sich die Spitze abgenutzt hat bevor der Stift leer ist. Hier nutzt sich gar nichts ab. Großartig.

Rotring es calidad. Y ese tamaño es ideal para detalles.

Ottimo
