I know we can’t sell them here, but is there a market for them in game?

The wow market discord. Dm me and I'll send it after I get home from work

WoW black market yes for sure.
On popular realms like Illidan, A52 etc

Gotcha,

I had a handful of really good ones on wow classic from launch that have just been sitting there… can’t remember what they were off the top of my head, I’d have to start my sub again
