I always see a bunch of people either asking or assuring others about 2175+ gun skins appearing on the night market.

They don't, sadly.

Also applies for the knives off these same sets. Knives off sets such as Glitchpop, Ruination, Sentinels, Spectrum, Elderflame, BlastX, Singularity...

People tend to downvote when being told this information, too. Which makes it the more baffling as wanting to believe otherwise for no reason lol

EDIT: Removed source of information as rule stated to not use direct links to other sites. Will be posting it in the comments
