Review: Reliable. ink flow joy. Refillable and sustainable. Zero waste. - 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.
Review: Superb instruments - I bought my set of pens 45 years ago as an apprenticed draughtsman, unfortunately I lost my 0.35mm and it had ink in it. It has been salvaged and back to the normal standard but I bought a replacement for an urgent task. First, Rotring are no longer made in Germany but still charge German prices. The quality has changed, not for the good of the instrument. Ink reservoirs no longer have chrome bands to strengthen them, the new ones will not be usable in 45 years and the plastic is a lower quality and poorer feel. When I bought my set in 1980 it cost me 2 weeks pay which caused murder at home as I had to pay a weeks keep extra in advance and another in arrears and go a week with no money to myself. It was a requirement so I had no choice,16 year olds today would be screaming at how unfair it was whilst I was happy I had a trade. You must clean them in diluted Rotring cleaner fluid every 6-8 weeks depending upon upon usage, daily 8 whilst now and again 6 weeks, soak and rinse then dry and back to work or storage. NEVER STORE THEM WITH INK IN, I was lucky mine were German engineering the new Chinese might not be so good but I will not be able to let you know in 45 years.

## Questions & Answers

**Q: Can you use acrylic inks in this pen?**
A: I have only ever put Rotring’s ink in these pens. However, when left to dry, this ink is waterproof. I can apply very wet watercolour paint over the top and it does not run in the slightest.

**Q: Does this include a cap for the pen?**
A: Yes the 0.7mm does include a cap clearly marked on the top end 0.7mm in white lettering. The pen reference No:- Art. 151 070. Complete with instruction detail sheet to advise on maintaining your pen should also be inside the Pen Box in which should be provided with your order.

**Q: Can you use cartridges instead of filling it from a bottle**
A: I know there's a difference between Isiographs and rapidographs, one only takes cartridges and one you fill up with ink as it has a little detachable tube you unplug and fill up with ink. It should be self evident when you buy it as the Isiograph will have a cartridge already installed in it....hope that helps?

**Q: Has anyone used acrylic waterproof inks with Rotring isograph?**
A: They would block the Pen
