I meet a Korean girl that is learning Chinese and comes to a Chinese English Exchange Meetup in Flushing, New York.  She told me about her Japanese Calligraphy pen set and showed it to me.  I tried it out and thought I would try to get the same set at Amazon.com for $26.  It took me some time but I was able to buy the same calligraphy pen set.  I have bought several similar pens in Japan a number of years ago.  These pens are good for quick writing and a quick practice without the hassle of the traditional way of using an ink stick and ink stone.  I think it would be very good at classical Asian painting for those who would like to try!
