Waterman Serenity Blue International Standard Short Cartridges
Waterman Serenity Blue is a delightful blue black ink, and the short international cartridge format is handy for many small fountain pens. I bought these originally for refills for a friend for a classic Waterman Lady Agathe, but I went back and bought more for myself. If you like blue-black, you are likely to love this color.
The short cartridge format is sometimes difficult to find, and I am very pleased to know Anderson Pens stocks it. Now I know where to go when I need more.
