Sailor Ink Studio is a relatively new line by Sailor, composed of 100 different hues! I will not attempt to classify and categorize the line, as it is done in great detail in this excellent overview of the full line: https://macchiatoman...erview-100-inks
I had my first exposure to these inks only briefly on-line when I had seen the interesting multi-hue inks #123 and #162, which are probably the most popular two of the whole line so far. On my recent trip to Japan, I was very happy to find that most of the large stationery store departments had the full Sailor Ink Studio line; some even with pre-filled demonstrator tester pens and paper pads to test the inks! Thus I was able to try out most of the line (it did take multiple trips to try out all 100 inks from this line, not to mention inks by other brands). With that said, the downside of having prefilled pens was that many had been sitting and gradually concentrating the inks contained in them for a week or two. And so some of the more saturated inks to begin with were super-concentrated by the time I was testing them, quickly sheening over on paper. It was not easy to imagine what some of those inks would look like in normal use back at home. Thus I focused on the less concentrated inks that showed more complexity--something different.
Please note: the colored stripes across bottle labels are NOT accurate representations of the inks (unlike, for example, Pilot Iroshizuku labels).
Ink Stidio #573 caught my eye right away. It was actually quite a surprise, as I was initially going to buy #273 instead. It turned out that #273, while being very nice, is just not as complex in writing as I had expected it to be. #573, on the other hand, is interesting indeed!
#573 is a relatively translucent ink of lower concentration, and so it has excellent shading properties, able to produce a wide range of hues from very pale faded terracotta to a deep off-black. There is a dark outline around dried ink lines which is readily visible and gives an extra oomph to the writing. For sheen lovers--you will not see this ink sheening in normal writing. You have to practically dump a lot of ink onto a page to finally see metallic green around the edges. But in all other circumstances, even writing on Tomoe River, you won't see this sheen. Instead, you will get a complex muted terracotta with an outline effect and a somewhat matte, chalky look. I seriously love this ink--it's simultaneously understated and very exciting.
Drying time is fairly quick, feathering is very well controlled, and there is even a good degree of water resistance without obscuring smearing.
My regular camera is having its sensor repaired, and unfortunately I don't know when I will get it back. I wanted to wait and do a more proper review, but my current fill of this ink was running low, and I decided it was better to put something together sooner rather than later. So this is a quick mini-presentation. I am certain this ink would be great for doing watercolor-style drawings because of it separating into very different colors in chromatography tests.
