rOtring Isograph Technical Pen, 1.0 mm

Not as fine a nib as previous nibs of this rating from this manufacturer

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.

The build quality is outdated. For the price you pay, i expected better quality materials. Nothing wrong with plastic, just that the barrel connector feels ready to crack and very flimsy. Otherwise, as a drawing tool, it works great, but not great if you angle the nib. I am pleased with it, just needs build quality.

I’m fond of these isograph pens anyway, but the .13 is superb for details and adding smooth stippled values.I haven’t found it prone to clogging, but it does need the odd gentle wrist flick if you’re doing dot work with it at the same angle for extended periods.My only criticism of it is the same one I have of all isograph and rapid-o-graph pens — that the pen body itself is made of the world’s flimsiest plastic and you can break them just by slightly over tightening the cap when you screw it back on.

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

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.

Maybe I’ve done something wrong but is it supposed to leak like that it’s very messy oh and this wasn’t cheap and no ink with it have to buy separately 👎

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.
