There do seem to be many "non-cute" but just cool / useful stationeries I could send, such as this eraser which is just a bunch of corners instead of being a cube so that you'll always have that best corner part of erasers to use: http://www.amazon.co.jp/%E3%82%B3%E3%82%AF%E3%83%A8-%E6%B6%8...
That's the plan, but I want to have some more subscribers in the cute plan to feel validated to do this pen japan thing at all. Each plan adds 1-2 days of work to my months.
