rOtringIsograph Technical Pen Master Set | 3 Fineliners (0.10mm, 0.30mm, 0.50mm), Mechanical Pencil (0.5mm), Compass & Accessories | 10-Piece Set in Case

I was hoping to try out a Rotring Isograph pen. The individual pens are quite expensive on Amazon, and then I saw this set for the same price as one individual pen (the sets seem to have gone up a lot in price since I purchased in October 2021). Anyway, for the price of one pen, I got three pens each with a different sized nib, an automatic 0.5 pencil with a tube of the ubiquitous HB leads, an eraser, a bottle of ink, all in a nice case with a clear lid that has various stencils cut into it.The pens seem to be made of a fragile plastic and I'm not too sure of their longevity. I guess most of the cost of these pens go into the nibs which are very fine indeed. They draw a lovely deep black monoline using the ink provided. The ink appears to be waterproof. I did find however that the lines for each size nib, .25, .35, and .50, were all slightly thicker than the equivalent size disposable fineliners that I use.The eraser was nice, you can't have too many pencil erasers. I have a number of 0.5 automatic pencils but this one is nice and a bit more 'tecky' than the others I have.The only complaint I have is that when first filling the pen reservoir using the bottle applicator I ended up with ink all over the place. You can't get the nosal into the reservoir to avoid an air pocket. And then a bubble of ink formed around the mouth of the reservoir which no amount of pricking would break. Perhaps washing the reservoir in soapy water first would help, but in all subsequent fillings I used an ink syringe to draw ink directly from the bottle and squeeze it into the reservoir from the bottom. Perfect. But perhaps a better applicator could be engineered.A nice set to try out these pens. I'm really interested in obtaining the very fine nibs, but the finer the nib the more expensive they are.

At £32, this set was an absolute bargain, as it goes for upwards of £80 elsewhere. I was looking for quality fine line pens with waterproof ink for not only my artwork, but also for technical sketches. I already own and use Pitt artist's pens as well as Pigma Micron pens, but as these are refillable they are much less wasteful and built to last.I received a set with .50, .35 and .25 pens with a bottle of the rOtring ink, which will last a while. But it also comes with a fantastically precise mechanical pencil, a decent eraser and a compass attachment that I don't really know what to do with, but apparently if you have a r0tring compass it means you can attach the pens to it. Finally the cover of the set is a very handy isometric template/ruler. Highly recommend this set.

I've noticed they don't get blocked like older models did of various manufacturers. An all round superb set and good value.

The pens and instruments are excellent but the ink isn't waterproof.

Very pleased with this. Rotring precision and quality throughout.

This is just such a cool thing to have. I use my isographs for my drawings. The ink flow is fantastic and the ink is perfect, the only dissadvantage I'd say is that the ink shows through if you fill in dark spaces with it. My dad loves the pencil and how it feels, I like it too but the pens are what jumped up at me. The ink flow is great and hasn't failed me for 4 months. You get enough ink to last you about 40 A4 pages full with ink. I got these pens mainly because they are more eco-friendly and cheaper in the long run you just fill up the reservoir with your ink instead of wasting money on buying one time use fineliners or plastic refill cartrages. I would buy again in a heartbeat. Great investment.

quality product and quality output

These arrived on time and well packed, but they all had dried ink and would not work. Perhaps to be expected but it did not say that in the ad. I had to spend ages passing them through a ultra sonic cleaner, but now work except for one.
