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 2 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!
