Question about Glorious PC Gaming Race GMMK Pro

With wired keyboards, it is usually the case that the cable is included.

It also says so in the product description:
"Keyboard features: detachable cable, programmable keys, RGB lighting".

I hope I was able to be helpful.
Greetings

I can confirm that a Type A to Type C cable is included. What you still need are switches and keycaps.
