rOtring Isograph Technical Drawing Pen | 0.10 mm | Refillable Fineliner Pen

(Doesn’t come with ink) This is the third one of these I’ve bought, in this fine size, so I can have one for white ink, one for black, plus a spare. Fine non splodgy line for crisp drawings. Prone to clogging but if you look after them they’ll last a long time.. Arrived well packaged in a nice box.

Arrived safely, perfectly packaged and worked well out of the box. Not the cheapest but no blockages, flow is excellent and quality good

Superb pens. I have been using these for years and years. My original ones have been going now since I was a student in 1982. Until now I never needed this size, and .10mm is extreemly fine and the smallest they make. Out of the box, I filled it (well I only ever half fill these) with the Rotoring ink, and a few shakes to get the ink through and its off......and hasnt faltered. Its wonderful to see quality products being made just as they were years ago and this is a wonderful bit of equipment. I recomend this and all the other sizes if you want to do this type of work. Of course, this is a specialist item....so use it for what it was designed for!

Arrived in good condition, works well,haven’t given 5 star just because its fairly new pen.Most probably will update after few months of usage

Love these isographs, so pleasant to work with them. Very rarely any issues and a quick clean always fixes the ink flow. Comfortable to use, easy on the hand (coming from someone who suffers with hand pain a lot), it's light, and stylish. I've been using my last one for over 19 years and it still works as good as new, bought this one more of a backup than a replacement. Recommend buying the cleaning fluid and cleaning the pen every so often just to keep it well maintained.

While the pen itself is working well the line thickness is a bit heavy. Looks more like a 0.2 or 0.25 rather than the advertised 0.10

This is a very good quality pen for the price, however do keep in mind that pens like this have specific purposes and they're not really intended for regular, everyday uses, so if you don't know why you would need a 0.1 mm technical pen then you're likely not at a point yet where this is necessary.

I love these isographs for sketching they are reliable and easy to refill.
