The rotring 600 is a legend amongst pencils. The solid metal pencil with its hexagonal barrel and circular knurled grip is one of the most sought-after writing instruments around. The 600 disappeared off the map some years ago, but bizarrely continued to be available in Japan. We've been importing these for some time, but rotring at last woke up to the fact that people wanted to buy them. 0.5mm and 0.7mm models are now available from rotring in Europe, but we still bring in 0.3mm and 2mm models from Japan, and these have minor differences in graphics.
No, we can't get rotring 600 fountain pens or spare parts for them - it's unfortunately long gone.
