Ratskin Clothing

Googling ratskin mostly turns up roleplaying games, with creepy science experiments a distant 2nd.

However:
Apparently Charlemagne would often wear ratskin, as it was a Frankish custom: Daily Life in the World of Charlemagne - Pierre Riche, Pierre Riché, Rich& - Google Books

while modern day it is possible to get ratskin cellphone cases: http://www.wirelessground.com/mov3racabugu.html

it’s funny how much from the game is actually possible.

Mushroom Wine, Ratskin suits, city stealing Masters… ;)
