On December 25, 2023 my Blue TWSBI Eco (Extra Fine) joined its comrades when it was filled with Vinta Cosmic Blue. I refilled it once; the last refill was on May 5, 2024. The pen was in use for 7 months and was emptied and cleaned on August 17, 2024, saying good-bye to its fellows.

Thoughts Before Filling

My lovely wife gifted me both pen and ink for Christmas. I’m thrilled to own both and they appear to be a great pairing. What else to do but fill the pen and enjoy!

Thoughts After Cleaning the Pen

This pen and ink combination was a delight, which is why I refilled it and have been using it. I’m ready to try a new blue pen so instead of refilling it again I’ll rotate it out to come back around again in the future.
