rOtring Isograph Technical Drawing Pen, Replacement Nibs, .30 mm

Fast shipment, great product

And many of those nibs last for six or eight years. My method is: several hundred words per nib, then a wash in the cleaning fluid and back into service. The nib, & even the fine wire, can take it -- the challenge is my needing a very steady hand, and very good small jeweller's pliers to hold the wire just above the nib, and then to drop it absolutely straight down in.It works for me, but only because I use the nibs constantly, so each one would get cleaned and re-filled every two days. Practice doesn't actually make perfect, but as long as the wire goes straight down in at the first drop, it's great. When that step fails, it turns into messy darned nuisance! I always do the cleaning over the sink, and wear an apron; but the payoff is a perfect nib ready for use at any moment.

Perfect pen for art, but you have to remember that when replacing the nib or using after some time you will have to shake for ages until the ink flows.

Da anni mi servo di pennini Rotring, e mai avuto problemi.Il risparmio con Amazon, poi, è rilevante.
