Kumiko Kumazawa of Pilot Corporation placed four fountain pens in front of me.
"Try them and tell me the difference," she said with a smile.
I am sitting at the counter of Pen Station, a museum of writing-related items in Kyobashi, Tokyo, that's run by Pilot, Japan's oldest maker of fountain pens. One by one I tried out the four pens -- one silver, one red, one blue and one with a transparent body. And yes, their touches were definitely different.
