Liquidraw Technical Pen Black Ink - 25 ml | Waterproof Drawing Ink | Refill Pot Compatible with Rotring Isograph Pens | Plastic Bottle & Screw-On Lid | Ideal for Drawing, Illustration & Calligraphy

Excellent

As advertised and reasonable price

I'm not a professional draughtsman so can't really vouch for the ink quality. It's black and writes OK on paper is all I can say. Only issue I had was with the bottle. Really wish I'd kept my last Rotring one and transferred the ink. The nozzle was solid so had to poke a hole down it. Always seem to end up covered in ink when refilling now - not quite sure how it happens but fortunately it seems to wash off very easily. Having said that it seems relatively waterproof once dried (in paper anyway). Works fine in my 0.25 Isograph and hasn't blocked at all so far.

I was having problems with the Rotring ink for my technical pen. They have changed the formula making it difficult to work with.This new formula becomes instantly permanent and makes it impossible to make tiny alterations . It also clogs up the pen and is harder to clean . The second photo shows a label that they are now putting on the new formula Rotring ink. This label never used to be on it. I draw clock dials and I have tried Liquidraw and it is more like the Rotring used to be. This was a great relief as I was wondering how I was going to find another product I could use successfully. If you are having any problems with Rotring ink,I suggest you give this one a try.

I accidentally got bleach on a red jumper (synthetic fabric) and I couldn't restore it with fabric dye. Took a chance on this ink and now the orange blob on my favourite top is no more. Not the typical use I realize but a very happy.

Very good ink

This ink is not suitable for Rotring pens as they claim. My 0.18, 0.25 and 0.35 pens are knackered due to this ink clogging them up. I have boiled the nibs to try and free them from the clogg. About £60 worth of pen nibs ruined. Not happy.

I have no idea yet about the ink itself, but the rigmarole for opening the bottle is ridiculous. Other reviewers have sensibly suggested pushing a suitably thin nail down the nozzle. That was fine, except that the nail then needed to be removed - and, surprise, surprise - the nozzle actually turns out to be detachable (something I had attempted unsuccessfully to make happen at an earlier stage). I am quite sure it cannot really be necessary to insert a nail in order to remove the nozzle unit, but that seems to be the route to success. Quite barmy (imho). UPDATE: I have since received a bottle of ink of a different colour. This time, the box also contained a needle with a grippable head. Problem solved (when one is fortunate enough to receive the pin!)

I didn’t like the quality. If I compare it with rotring ink, it looks different on paper and on the bottle. It has a different viscosity.

Très belle couleur. Similaire à l'encre rotring

Bon produit

Belle couleur, bon pouvoir couvrant, compatible avec les rotrings isograph, meme très fins. Cepandant elle sèche beaucoup plus rapidement que la marque rotring. (Mais oui ils ne font pas de orange :/)

preiswert und Tinte in Ordnung
