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. The pen was in use for 4 years and was emptied and cleaned on January 22, 2023, saying good-bye to its fellows.

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!

Thoughts After Cleaning the Pen

One thing I have learned about this pen, is that the nib needs a bit more fine tuning. It’s not as nice as my other one. One thing I learned about the ink is that it eventually becomes sticky in the pen and requires some priming or washing. The pen itself looks to be in good working order after a couple of years containing an iron gall ink. I doubt I shall do something like this again in the future though.
