Assorted Cartridges for Calligraphy Pens

These are various colored ink refill cartridges for calligraphy pens. By the brand Manuscript, they work with Manuscript calligraphy pens and maybe others, but that is only what I have tried with their brand of cartridges. These are all unused, though I opened the packaging when I was looked at them. Comes with 5 different colors: green, red, brown, blue, and black. They write very smoothly, and are great ink refills. excellent for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
