I bought this pair of blue extension cables to help with the USB port jigsaw puzzle on my KVM Switch. In my work from home setup, I share my two screens between my work laptop and a mini PC that I use for personal business that doesn't have website strips or USB lock. But the webcam, keyboard, and mouse microphone cables stick out and sometimes get clogged in that small section in front of the KVM switch. So with these blue wires I can connect one of the devices to the left and one of the devices to the right. The cables are long enough, but not too long, to add to the cable stock.
