I tried this ink in a normal fountain pen, and it was completely unusable as such. Very leaky, lots of splotches, would not write. Comparatively, the Jupiter's Butter Ocean will actually write in a fountain pen, although it is still a bit tricky and rather faint.

This ink is also very faint on paper compared with other S+S inks attempted (with the exception of Mercury in Gemini which is more or less completely clear). You might consider using it in the place of water on an ink block of you want to write something legible. For petitions or other writing to spirits I expect this would still read fine.

I'm going to try using it with a fillable marker soon and will update this review with the results of that experiment.

I have been moved several times to draw circles around my ankles with this. The days that I have done that, its been a speedier/get things done, dance with rainbows, but also no time to smell the roses. Perhaps this was slightly foolhardy, but I feel like that is in line with the spirit of this ink. Sort of like borrowing winged sandals - it will absolutely get what you need done, but you best be prepared because you don't control the speed through which the day is happening.

I highly recommend this product and use it regularly. I love to get blank notecards and then use this ink to write glyphs and names in order to ask for help, give thanks, ect. It feels *good* in the hand and is surprisingly easy to write with...I wasn't sure if I was going to be able to actually write with the brush cap and you totally can. I highly recommend!

I used this to draw a sigil on a petition for a road opening candle spell. The candle has been burning FAST, with an abundance of daily results affirming its success. Super effective. I’m really excited about this resource!

I have used this to draw a sigil on my work computer when the internet was being shoddy and it fixed itself really quickly, also every package I have mailed has had this ink on the outside and has arrived ahead of schedule & undamaged. I am excited to explore what else it can do as it seems to act as a flag for items that im asking mercury to take special care of. love love love

I wear this Ink occasionally for supporting articulate speech and when otherwise in need of a Mercurial boost. I most often draw simple Mercury sigils on my skin with it or apply the Ink to parchment paper during ritual. The Ink can be painted on faintly under clothes to avoid having it seen by others, if needed.

The lush ingredients and the subtle tone make this stain very approachable and workable. If you use it to draw sigils on skin, they will likely not be noticeable to others out in the wild (at least in my experience with the brush cap provided). Especially for this series, ink/stain seems so appropriate and intuitive to use for Mercurial devotions and so many other uses. Tis the season to put a little dot of it on one’s mail, for instance! Oh I just can’t get over all the organic ingredients- it feels like a whole table of yummy offerings condensed in a versatile little bottle. Don’t sleep on the stains!

I got this in the secondary market and it’s great! I didn’t know if I would like working with an ink and couldn’t really afford to not like it, but after trying it once I’m contemplating buying double as soon as I can. Can’t describe the power and clarity. I’d like this forever.
