rOtring Isograph Technical Drawing Pen | 0.25 mm | Refillable Fineliner Pen

These are my favourite pens! Such fine lines although they can be bothersome to clean. I use these for drawing rather than writing and the quality is impeccable. They are on the more expensive side but nowhere else can I get such consistently fine lines. I like that they are refillable (the isographs so much more so than the rapidographs). For good consistent flow without having to clean them, these pens need to be used regularly. Weeks without using them can lead to splotchy lines or blocked pens.

As expected from Rotring, perfect engineering

Very good pen for technical drawing, extremely consistent and controlable dark lines every time. Only dropping down from 5 stars as they can feel very scratchy to use and the tiny wire filament is super delicate so you need to be careful during maintenance.

I wanted to draw a detailed map with handwritten street names. I tried a felt-tip pen with 0.5mm nib but it was too thick. The Rotring 0.25mm nib was perfect for the job and I am very happy with it. I can recommend it for fine, detailed work.

does not work. Also the pen given to me has like an ink that dried. May mean it was used before. Totally unhappy with this purchase.

Excellent tech pen. Bought for my son at Christmas replacing an older one. Detail is super in all the drawings he has done Fast post and well packed and very good value

Wonderful friend...my current bestie

Very fine nib, a joy to use.

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.

You cannot get a better isograph technical pen then Rotring. The line size is always consistent and the rotring ink used in the pen is smudge proof and water proof.. It also dries really quickly. If u r into stippling or pointillism kind of drawing then Rotring is the best.

Ich will nie wieder was anderes

Super snabb leverans

Pen consistently lays down a fine line. I’m using the Rotring ink and the pen has not clogged even when sitting unused for several weeks. I use it for sketching and watercolor highlights. It’s great for small drawings where I need detail with a very fine point. As others have said, this is a technical pen, and must be used fairly perpendicular to the paper. Once you grow used to that, it’s great.
