On May 20, 2016 my Clear TWSBI Diamond 580 (0.4mm CI) joined its comrades when it was filled with Paradise Pen Black/Blue. The pen was in use for one year and was emptied and cleaned on August 14, 2017, saying good-bye to its fellows.

Thoughts Before Filling

It’s been far too long since I’ve used my smallest italic nib, and I’ve been enjoying the last few blue black inks I’ve tried. I figured I’d give this a try, and give myself permission to put it back in the bottle if it isn’t a good fit, though I don’t expect that in the least.

Thoughts After Cleaning the Pen

I found that I was not often in a blue/black mood while this pen was full. The nib was also quite fine so it took some time for me to write this pen dry.
