CANETA DANIFICADA, PÉSSIMO ATENDIMENTO...
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.

Feinste Linien und Nachhaltigkeit
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.

Best fine tipped pen out there
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
