This is my go-to cartridge...
September 13, 2014
This is my go-to cartridge in my Tradio. I use this all the time for general
writing, notes, sketches. It bleeds just enough when some watercolor is applied
to it, but not too much. I get compliments all the time both on the pen and the
line quality I get with this cartridge.
Personally, I prefer the black, but have used blue and red in the past with the
same exceptional results.
