From this point, I started using different pens which I had found in an antique store in San Diego during my trip to the States. On the left is a Waterman Junior filled with Aurora black ink, and in the center is an English Waterman 515 (ca. 1947) filled with Havana brown ink. Both pens have incredibly flexible nibs. The steel nibs on the Esterbrooks are great, but there is definitely more flex and less scratchiness to the 14 carat gold nibs of these these old Waterman pens.

The pen on the right is a Pilot brush pen which I bought here in Tokyo. This is a cartridge type, but I took a chance and just filled the barrel with a brown ink wash. So far, it has not leaked out! I am still using a Strathmore 3.5" X 5" Premium Recycled sketchbook.
