rOtringIsograph Technical Drawing Pen | 0.35 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.

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 love this pen, keep it clean and it will go on forever.

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 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.

Good quality product at a very good, affordable price. Impressed by how quickly it arrived.

Amazing pen. I use it all the time for writing and drawing and it never let me down. Perfect smooth line every time.

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.
