Hi!
I did (an admittedly) quick search and didn't see anything about this, so wanted to share my fandom-esque find.
Pinnacle Polish, an indy nail polish company, has a small series of polishes inspired by Brandon's works. The Iridescent Tomes collection and a set of three glitter toppers (a black one called "Ruin", a white one called "Preservation", and a mix of the two called "Harmony.").
In case there are any other nail polish and Sanderson enthusiasts out there, I wanted to share. Go check them out AND support a small business.
I might or might not (read: definitely do) have the glitter toppers on right now in a manicure I'm calling "discord" just for my own entertainment.
I am not Pinnacle Polish nor in any way affiliated, but figured this counts as a fan work.
