DIALOG NOTEBOOK is a notebook designed by Takuya Takahashi, the head of "Everyday Stationery," a Japanese web media about stationery. It is small enough to fit in the palm of your hand, making it the perfect pocket-sized notebook. It uses "Kinbishi" high quality paper, which was developed in the 1960's for use in bank ledgers, and it is known for its smoothness and strength. It works well with all sorts of writing instruments, including fountain pens, with minimal bleed-through.
