The pen I usually use is Sakura's .005 felt-tip "micron". It easily makes lines around half as wide as the period at the end of this sentence (but can also make thicker ones depending on how its used). The offical line size is said to be 0.2mm.

(Hm... for some reason the links don't work for me so just look up "Micron pen .005" on google)
Anyway, my question is if anyone knows whether there's a smaller felt-tip pen out there. I'm talking needle-small lines. The only thing that makes this seem a little hard to imagine is that it would be so easy to crush the tip... unless it was made of something stronger.
So anyone know of the "smallest" felt-tip pin out there?
