Squid Ink Sepia Ink! This is squid ink sepia ink made with genuine squid ink, sold by a fountain pen expert. There are dark (for calligraphy) and light (for fountain pens) versions, and this is the light version. It has a very unique smell. I used it to fill my pen 3-4 times. The color is very tasteful and wonderful, but it dries easily and requires a specific fountain pen. The airtightness of the cap is slightly low, and the water has naturally evaporated, leaving about half the original amount as shown in the photo. Adding a little water might restore the original concentration, but I didn't try it. Several metal balls have been added to the bottle to stir the ink particles, which tend to settle at the bottom. Due to this being a used item, returns are not accepted. Please understand that there may be scratches and ink stains before purchasing.
