rOtring Isograph Technische Tekening Pen Vervanging Penpunt | 0.50mm

Mijn oordeel is niet voor amateurs en moeilijk te reigegen

Oggetto nuovo

Ein hochwertiges schreib und Zeichenutensil. Leider fehlt ein, meines Erachtens dazugehöriges, Tintenreservoir.Daher ziehe ich zwei Sterne ab.

Alright people, let's try a bit o honesty. These pens are very fine; and that means like a good camera or tool, they require an amount of care. I can attest to having been lacking as such. I either was too involved in the work; or I was too, sporadically using the pens. Personally, I find these pens to be the best, unless, you go to markers. AND yes, markers have become phenomenal- some being reusable like, COPICS. In any case, all versions of technical pens are FINE instruments -- especially the finer widths, which are any "0" or finer points. They will slightly jam or clog unless you are as persnickety about care as you are about using them. As I admit, I am a case in point. I therefore I recommend confidently the following process. Go to your local drugstore, and buy a disposable electric toothbrush. They run on a triple A battery which you WON'T have to install, and I've known of more than one manufacturer. When you're having a pen problem, disassemble the pen ONLY as far as you would be able to rinse it -- and not to where you've completely taken it apart. Take a rubber band and wrap around the end of the toothbrush. Carefully slip the pen point assembly through one of the loops of rubber band to hold it snugly against the toothbrush end and ideally, not against the actual brush. Turn on the toothbrush and submerge in water( I use an old plastic vitamin bottle ) or diluted pen cleaner or full strength cleaner. Probably it would work with mild soap, but stick with water or pen cleaner/water combos. Because I have had to come up with this, I try to be more careful of my pens as I like using them more than cleaning them.---- hey, update, I'm always learning- scrap some of the above and get yourself a small and relatively inexpensive ultrasonic jewelry cleaner.

Unterscheiden Sie dringend zwischen Isographen und Rapidographen. Weil die Ersatzteile anders sind. Bewahren sie ihre letzte Patrone auf - auswaschen, trocknen und mit Tusche aus der Flasche nachfüllen. Patronen für den Rapidographen gibt es nicht mehr.

Good fine nib
