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 one year.

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.
