Product title says Rapidograph, image shows Isograph. Which product is it, please?

The images shown are not ones we have listed. This happens with Amazon listings. If our description is for rapidograph and the code starts R155 then it's rapodograph. The only difference with the two products is the way you refill the ink. Rapidograph is a cartridge based pen, so once it's empty you replace the whole cartridge but Isograph when the pen is empty you refill the cartridge

What colour ink does it come with, or do you have to buy the ink with the pen.

You’ll need to buy the ink separately unless it’s offered as an option. Only use the Rotring stuff as the pens, especially the fine ones will clog and become useless.

Is this the thickest nib .

No there are several nib sizes rising to 1.0 from 0.1

is the 0.10mm rottring more fine than the micron 0.05 ??

If you mean the Pigma Micron 005 which has a line width 0.20mm then the Rotring isograph 0.10mm will be finer.
