【New, Unopened】QRD N5 Wireless Controller for PS4 and PC

I have three PS4 consoles, so I bought multiple units, but it seems I won't be using them after all, so I'm selling them. They are brand new and unopened.
I've priced them lower than the new retail price of 6,499 yen, so I believe this is a great deal.

The sticks use Hall effect sensors, and it comes with a full set of features including back buttons and macros.
