Overall, (like Planetary Motion from this same set) I enjoyed the ink but I’m not in love with the tiny 5ml bottle. I like the lovely shading and the dark color, but it’s not a must-have for me.

I used a Lamy Safari Petrol with an medium nib on a Taroko Enigma notebook. The ink had an average flow.
Overall, I enjoyed the ink but I’m not in love with the tiny 5ml bottle. It’s rather spendy for the tiny amount of ink, and it is a bit messy to fill your pen with since you can’t put the nib straight in the bottle.

Sailor’s Sailor, despite having a slightly silly name, was developed to commemorate the 15th anniversary of the Sailor Ink Studio events. I dream of one day being able to attend an Ink Studio event and having Sailor’s ink mixer Osamu Ishimaru make me my own custom ink-it’s on my bucket list. Thanks to Shigure Ink for sending this ink over for review!

I used a Pelikan M600 Turquoise with an extra fine nib on a Taroko Enigma notebook. The ink had a wet flow.
Overall, I love this ink. I love that it shades and sheens, even in an extra fine nib. The color is great, the shading and sheen are fabulous and the wet flow is lovely. I will be using this ink often!

I used a Bonecrusher Studios pen with a Regalia Writing Labs Crossflex nib on a Taroko Enigma notebook. The ink had an average flow, but struggled to keep up with the super wet flex nib. It looks much darker in this wet nib than it does in drier nibs.
Overall, it’s an interesting green ink, but it does struggle to keep up with super wet nibs.
