How many royal blue fountain pen inks are there? I think I own 6 or 7 myself. So for the next few Ink Dupes, I’ll be comparing them to each other. You’ll be getting an Ink Dupe post every week for a bit so I can power through these.
As a side note, Bert’s Blue (an exclusive for Bertram’s Inkwell) is sold out, and Tyler of Organics Studio has mentioned that he can’t find the recipe. So, for the time being, that ink is discontinued. Maybe in the future it will be available again. Sadly, I couldn’t find a review for Bert’s Blue, so you’ll have to do without.
