Here is Vanness Possum Pie (aka Possom Pie/Opossum Pie, etc.), their limited edition Thanksgiving 2025 ink. I received a 5ml sample of this with a recent order.
It’s dark brown with some shading and a tiny hint of greenish sheen if you can make it put down a lot of ink. It’s not a bad shade of brown/sienna. The sheen in the large swatches doesn’t show in the writing at all, which is good because it’s not exactly pleasant. (I’m also glad it is not scented!)
It is very dry! On Col-o-ring it was struggling to put down a line on the thin angle of the stub nib. Looks much nicer on Iroful. Midori was OK.
Scans
The scans are fairly true to color here. The photos below are a bit lighter.
I copied the name exactly from the sample tube label thinking they misspelled it on purpose, but on their website it’s “Possum Pie” and I quote “we know it misspelled” (sic) 😆
Photos
In this photo you can see a little bit of the sheen.

Microscope
You can tell in the microscope photos that the ink goes down a bit thin and light overall.
There is some shading on Midori. Iroful does more of a gradient instead of the usual way shading happens.
Chromatography

The chromatography starts brown then there is an area that is very faintly pink

Nothing too noteworthy under UV light, but there is a slight blue halo past the leading edge.
Group Photo
The group photo is a bit lighter than it usually appears, might have been something slightly off in the light or exposure.

Verdict
The color is nice, but it’s not an ink I’d use regularly. Between being overly dry and having some sheen I wasn’t crazy about, it had too many drawbacks for me.
