On January 13, 2019 my Blue Wing Sung 3008 (IEF) joined its comrades when it was filled with KWZ IG Turquoise. I refilled it once; the last refill was on April 21, 2020. This pairing has been in use for 3 years.

Thoughts Before Filling

I bought these Wing Sung pens precisely because they are cheap, so I won’t care what happens to them, thus they are my experimentation pens. I want to see what this iron gall turquoise ink does to a demonstrator, so here we go!
