rOtringIsograph Technical Drawing Pen | 0.25 mm | Refillable Fineliner Pen

This is a great pen.It draws smoothly and reliably. Takes India Ink which is waterproof and permanent. Way cheaper and sustainable to use a refillable pen than keep buying disposable pens. I bought a 250ml bottle of ink; way cheaper than the tiny ones. The steel nib will last forever. I use it most days. But if I leave it for a while, a good shake and the ink flows like a dream. I had been using cheaper brands, which were fine for a while, and then clogged and stopped working, even after extensive cleaning and faffing about. Grrr factor 10/10 after several months of use. As an artist and not a technical draughtsperson, I really rate these pens. Mine is a 0.6 nib. Can't vouch for the reliability of the finer nibs.However, it is too easy to over-tighten the grey nib holding section against the handle / barrel. Mine has a hairline crack, allowing the barrel to rotate a bit and be annoying. But it does not affect the drawing function, or ink flow, just the handling of the barrel. Still useable, but would like a better quality plastic at that point in the design. I have not been heavy handed with it. It was just a bit weak there on the thread.Having said which, it is far superior to the cheaper brands. I wasted money buying several cheapos, thinking I had simply bought a rogue pen initially. Not so. The working parts were just not as good as Rotring. Invest in the best.

Everything okay.

Used for 40 years and still the best. Can't say more.

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.

If you're in need of a pen with a really thin tip - this might be the one for you. It doesn't come with any ink or means to fill it; but it's kind of assumed that you own all this stuff. I had ink, but no filly thing, so I just used a syringe I had lying around (a measuring syringe - I'm not a smackhead!)If you've got hands spades and arms like a stevedore, you may find the tip a little delicate - I had to ease right up on my heavyhandedness to adjust for it, but I love it now. The body on mine has cracked, but I've dropped it a few times, so that's probably on me.

I have been using Rotring pens for many years and was finding it impossible to replace my two worn out models. i was delighted to find my replacements via the Internet {namely Amazon}. The replacements came very quickly and i have had much pleasure in using them for a variety of tasks.

I bought this pen last year because I was aware that the Rapidograph, which I usually draw with, was being discontinued. I have not needed to use this Isograph until now, and I have just discovered that the refillable ink cartridges were not included with the item, so it is unusable. Naturally the return window expired months ago, so this one is a complete waste of money.

I really thought that this would be the ideal fine-pointed pen for me, after the tips on a succession of Pigma Micron 005 pens sunk into the pen within days. Sadly, I've been disappointed as the Rotring is very difficult to use - if I lift the pen from the paper for a second or two and then try to write or draw again, the ink seems to have dried up or stopped flowing and I need to give the pen a good shake to get it going again. It's not ideal at all when your pen stops working if you take the briefest of pauses.Given the cost of the pen, both the intermittent flow and the fact that it's plastic and doesn't feel premium or likely to last long are extremely disappointing.I should have gone for a cheap fine-point rollerball or gel pen and saved myself the hassle and money.

I think this is the kind of pen, you either love it or you hate it. I love it, but it is not without upkeep. Occasionally I forget about it for a couple of weeks, so I just run the tip under warm water and it comes back to life.

These pens are amazing but I am going to warn any new buyer; proper and frequent maintenance of these pens is crucial or a clogged tip (or dried ink) will disrupt the ink flow permantly. If you are serious, I would recommend an ultrasonic ckeaner. These machines will remove every drop of ink from your tip (far better than running your nib under a tap) Just watch that tip, it’s very senstive and can bend just like that.

Reminds me of a fountain pen, but with a nib that provides a clean, straight line. As expected with Rotring, it has a very nice weight, simple to fill and a pleasure to use.Highly recommended. (I'm going to order a fine-tip set for Xmas)

Many rotrings come broken like mine did. The company uses cheap brottle plastic not suitable for a 40$ pen.
