Yes, it's the exact color of the juice that leaks out of just-baked blueberries, so appealing that filling a pen with this ink will make you hungry. Don't drink the ink, though - writing with it is also completely satisfying!
One thing to note is that this ink has a little more show-through than many of my other inks I use. I have it in a M nib pen and can't use it in a Leuchtturm 1917 because it's too dark on the proceeding page.
Luckily, there are other notebooks out there!
This is from my June Inkredible box. It's a very matte ink. It doesn't pop or shade well, for me at least. I can see it as a good ink for the office though.
