On August 17, 2024 my Kyanite Blue TWSBI Vac 700R (Extra fine) joined its comrades when it was filled with Noodler's Ottoman Azure. This pairing has been in use for 3 months.

Thoughts Before Filling

I took my time choosing the ink for this pen. Ottoman Azure was what my gut told me would match, and after doing dip tests of half a dozen inks it was the one I chose. Already I enjoy writing with this pen, as I have with all my Vac700 models. There’s a chance this one stays in rotation for months.
