2 controllers, they’re sold in a 2 pack. Honestly for the quality $21/controller isn’t that bad.
I wouldn’t buy the NES controller but I have the SNES and N64 controllers and those are really good wireless recreations of the classic controllers, and with a BlueRetro or 8BitDo adapter you can get a brand new, low latency, wireless controller set for your actual SNES/N64.
This is a really good thing, and something I wish all companies offered for their classic consoles.
