does the 2-pack come in one package or each in its own packaging?

Each cube is packed in a separate box and then packed together in a large box

Is there a tensioner screw on this…… make it slide easier/quicker

Yes there is a tensioner screw it’s a bit hard to get to because you have to pull the layers apart a bit like some other 4x4s it corner cuts ok but feels a bit sticky but is better then other 4x4s I’ve had

What does 3 cube 4x4 means? Does it include 3 rubics cubes?

The number in front if just the way Amazon made the system so option 1 is a 3x3 option 2 is two 3x3 option 3 is a 4x4 and so on
