rOtring Isograph Technical Drawing Pen Replacement Nib | 0.18 mm

I've been using Rotrings for over 40 years and for the past 3 years I've had problems with the 0.10 Isograph nib. Some haven't worked at all. Some have given up after a day or two. Some have worked for a while but needed a lot of shaking and cleaning and then have eventually died on me. Have Rotring outsourced them? The previous full pens I bought were made in India... they were the recent ones that didn't work.Now the good news. The two nibs I've just purchased arrived very quickly and thankfully work superbly. I can tell by the flow of ink and the 'feel' of the nib on the paper that they will last! I'm very grateful and when finances allow will buy a couple more.

The best ink pens on the market for very intricate drawings but sadly the nib clogs very easily!!! Sometimes it starts working again after cleaning (you have to purchase the special cleaning liquid) but sometimes completely stops working. Shaking the pen is vital. I couldn’t find any other replacement pen so I keep buying Rotring which is not cheap...

And many of those nibs last for six or eight years. My method is: several hundred words per nib, then a wash in the cleaning fluid and back into service. The nib, & even the fine wire, can take it -- the challenge is my needing a very steady hand, and very good small jeweller's pliers to hold the wire just above the nib, and then to drop it absolutely straight down in.It works for me, but only because I use the nibs constantly, so each one would get cleaned and re-filled every two days. Practice doesn't actually make perfect, but as long as the wire goes straight down in at the first drop, it's great. When that step fails, it turns into messy darned nuisance! I always do the cleaning over the sink, and wear an apron; but the payoff is a perfect nib ready for use at any moment.

I've used these pens (especially the fine ones) for years: they used to work perfectly straight away but progressively deteriorated as the tubular nib began to block with very fine particles of the paper dug up by the pen. This one did not work at all straight away despite fallowing the instructions. I had to rinse the nib under hot water and then suck the ink down the tub; then it worked. Luckily it's not toxic and I'm still here!

I have used these pens before and they are the very best out there. I am an illustrator and require to work with a very fine nib and this pen does the job. My only advice to anyone thinking of buying one of these Rotring Isograph pens is to also purchase a bottle of the Rotring nib cleaning fluid. I never leave my nib in the pen after use as it dries up and becomes impossible to clean or use the nib again. After use I wash the nib carefully in running water then drop the nib gently into the bottle of cleaning fluid and leave there until I need to use again and this keeps my pen in tip top condition. Hope this has been helpful.

The product arrived promptly and was as described. I am very satisfied.

Have been using 0.13 Staedtler which work so much better but are out of stock. Got this and it's 0.2mm wide, it's far wider line than the apparently bigger 0.13mm.Got a second, thinking it might be a one off and nope still too wide. Why did they stop the 0.13 nib and make this one wider, we need to work with fine lines, this is rubbish

I ordered this Rotring 0.13 nib because it was sensibly priced for a drawing instrument that has become a rather old fashioned method of drawing. It has been added to my stock and will be pressed into use when the existing 0.13 pen tip wears out.
