Hollow Cube is a 3x3 special-shaped magic cube invented by Katsuhiko Okamoto in 2008. It is different in structure from the regular 3x3 cube
It's just looks like a normal 3x3 cube, but has no centers.Without the help of the centers,so it becomes a little more challenging to solve
The mechanism will baffle you since there is no core, but it works surprisingly well.This cube is an interesting and amazing puzzle
If you're looking for an extra challenge, we will recommend it for any serious collector or even for someone starting with cubing affairs
This is a great and novelty gift for all ages.If you are a beginner, you can try it. If you are a professional player, this is what you need
