On January 2, 2023 my Cerulean Blue TWSBI ECO (Extra Fine) joined its comrades when it was filled with Noodler's Navajo Turquoise. This pairing has been in use for 11 months.

Thoughts Before Filling

I want to use my new pen and I like this particular shade of turquoise, so I’m going to put them together and see how it works!
