Hi, On the 20th May 2016 I am lucky to be going to Tokyo and Osaka. What would you contemplate buying that is interesting, different, you cannot buy elsewhere, (especially the United Kingdom) etc. and from where? I am into Urban Sketching so also want to visit there art supply shops It could be pens, strange nibs on pens, pencils, paper, inks, calligraphy (like), sharpeners or anything else pen, calligraphy or stationary related. All suggestions no matter how wild and wacky will be very welcome
