QiYi QiMeng plus 9CM 3x3x3
From the photo this may look like a warrior S but it is actually 9CM in size making it the largest reasonable speedcube commercially available, obviously much larger cubes do exist but they are so big that they are hardly useable. The purpose of this cube is meant to be to teach people to solve due to the size making it easier for people to see what you are doing from a distance.
