On July 25, 2020 my Orange TWSBI Diamond 580AL (Extra Fine) joined its comrades when it was filled with TWSBI 1791 Orange. This pairing has been in use for 9 months.

Thoughts Before Filling

I’d be remiss if my first use of TWSBI’s orange ink was not in their 580AL orange pen. Since I already have an orange ink in a pen, and it has an italic fine, I opted for an extra fine nib on this one.
