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.

When looking at the swabs for these two in my swab notebook, they looked almost identical, but in this test, I noticed a distinct difference. So, while this isn’t exactly an ink dupe, I felt it was worth sharing for those who, like me, thought that they are.

Also, Colorverse Photon is only sold in a two-pack with Gluon. The price listed for it is the total price for both, and the price per ml is the price of both bottles divided by the total mls (80) of both bottles.

For those who don’t know, BWIPS stands for Baltimore Washington International Pen Show. The BWIPS 2018 ink was a special edition ink that was given away around the show that year. Because it was such a small batch, I couldn’t find an ink review, but I’ve found it to be rather dry.

Here’s another “fan request”. While they definitely look different in chromatography and swabs, I think they’d be indistinguishable in all but the wettest pens.

Robert Oster has two lines of ink: Signature and inkArt.ink. The former is readily available. The latter doesn’t appear to be available currently. I used the Signature ink for my comparison, but, for giggles, I included a chromatography strip of the inkArt.ink (IAI).

For those familiar with Organics Studio, you’ll know that at any given time, a certain ink may or may not be readily available. For that reason, I’m dubbing it “usually available.”

A little side note before I jump into the comparison. I believe that Australian Syrah has recently (since I bought my bottle) been renamed to Australian Shiraz. If I’m wrong, please let me know and I’ll adjust this post accordingly.

Finally I get to compare inks that aren’t completely identical. These two are close enough, though, that if the new Sailor Jentle prices are too steep for you, Jade is a good alternative. They’re almost indistinguishable in normal writing.

For those who aren’t aware, I’ve heard that the 50ml Sailor Jentle bottles are going away to be replaced with significantly more expensive (price per ml) 30ml bottles. If you’ve heard otherwise, please let me know.

I just so happened to purchase samples of both of these at the same time, so they got swabbed right next to each other. I couldn’t miss the similarity. So if you missed out on Kabayaki, you can grab a bottle of Nostalgia. Unfortunately, I can’t find a review of Kabayaki, so you’ll have to do without.

This is my second Diamine vs Montblanc, and I have to say Montblanc is seriously disappointing. For the price, I would expect SIGNIFICANTLY different colors. These two are so similar I can’t help but wonder if UNICEF blue is just rebottled Aqua Blue.
