It's the world's thinnest gel pen! The tip is so small you can write words on a grain of rice. The tiny needlepoint tip of this pen will let you scratch notes into the smallest of places. The Uni-ball Signo Bit line is famous for their small and thin writing ability. This product, already rare in the US, might become even more rare as certain colors have started to become discontinued from Uni-ball Japan. Get them while you can!

This pen is wonderful....

This pen is wonderful. Unlike the black version, the red ink tends to flow out consistently and smoothly, although this does mean that it's not quite as good for "sketching" as the black pen. Its line is much thinner than the red 0.25mm Hi-Tec-C pen, but still smooth. The design is also very nice, and comfortable. I can also highly recommend the orange version of this pen, which has a very pretty ink colour; unfortunately, it's not sold by Jetpens anymore.
The design of the pen...
December 1, 2008
The design of the pen is really nice with a splash of color from the cap of the pen to the tail section letting you know which color your using.
Writing with the pen is pretty comfortable because of the molded plastic on the body. Your able to make some really fine lines with this pen as I realized with the rice test. I was able to write clearly on a grain of rice the word 'pens'.
The is some scratching noise when writing with this pen other then that this is a great everyday pen.
