General

I see it from time to time, but yea, it seems to be unobtainable atm. Ya best bet is to get someone to anvil it for ye.

the black one waaay more flex imo

I'd say it really isn't a thing, but the actual rarity of the mustache now is consistent to that of
A Floral Print School Uniform. Either no one bothered, hacked, or took a long time to get it.

Got blue one and a majority of the beards on my mules

I have one in Scania

I opened 300 boxes trying to get the blue mustache during the event

It was well worth it

they are a discontinued item, meaning they are no longer obtainable. They are very rare
