Found in a lot of Tombow rollerballs from the Write Shop, in Los Angeles.  These pens have very little information in English available.  These Tombows seem to have been sold or given as samples to Mr. C prior to Tombow having significant marking in North America. A common brand in Japan, but almost unknown at the time in the USA.  My Japanese friend is shocked we had something like this in our back stock.
