Faber-Castell 148110 - rollerball pen AMBITION precious resin, metal tip: 0.7 mm
Unfortunately Koster an original spare air of a little over 3 EUR!
After much research I ordered these mines since the appearance of the face is similar to the original.
And so it was. Fits perfectly, writes great and costs only a fraction (55 cents) in contrast to the original.
So absult top !!!
