Technical pens, everything about cleaning, unclogging. Rapidograph, Isograph, Rotring, Fabercastell

In this video I will discuss about Technical Pens (permanent and disposable ones) and how to maintain and keep them running without actually damaging them. Permanent technical pens became less popular today due to disposable ones introduction, but they are quite suitable for inking, pen & ink, calligraphy, drawing, lettering, drafting and... . Watching this video is highly recommended to all artists, graphic designers, calligraphers, drafters, and other art or engineering related professionals. Stay tuned 😉 and don't forget to subscribe for later videos and give me a thumbs up 👍 and it's worth mentioning that the term Rapidograph was actually first used by Rotring and not the Kohinoor and this was mentioned mistakingly in the video and needed to be corrected. #penandink #isograph #rotring #fabercastel #staedtler #polygraph #hope #kohinoor Sketching, pen & ink, Rotring isograph, PELIKAN GRAPHOS, fountainpen, Technical pen, Rapidograph
