I love this color and will buy again! But it takes at least 15 seconds to dry on Hobonichi paper. Probably user error because I was testing it immediately after replacing.

### ⭐⭐⭐⭐⭐ Exactly What I Was Looking For
*by J***N on December 18, 2023*

These are a staple for my fountain pen collection. I love the color because it is not fully black, but a very very dark blue, giving a unique hue. These are so simple to use, just popping in and out if I do not feel like using the ink converter. The do tend to run out rather quickly depending on the nib size you use and without showing signs they are getting low, recommend having a backup with you.
