I have got to get a set of these. My wife uses the 0.3mm pens when she writes letters and I occasionally borrow them fro myself. Its great, you can write as small as you like and still read it. The 0.18mm pens will be amazing, and yes I’m going to try and write on some rice (I’ll post photos once I do that)

It’s the UniBall Signo Bit 0.18mm pen from Mitsubishi.
There’s a pen war on Japan, in case you didn’t know, to produce the pen with the finest point.
Pilot came out with one having a ball diameter of 0.3mm in 1994.
Now comes this new player with a point twice the width of a human hair.
The pen required the invention of a special friction-reducing ink.
Mitsubishi has sold 4 million of the pens, which come in eight colors, for $1.75 apiece in Japan.
They cost $25 for a set of all eight colors…
