Here I present a very rare factory produced cornerless cube. It carries the Space Cube name, and it was produced in Japan. The Space Cube name is not unique to this cube as I have seen cubes of other shapes under the same Space Cube name. Another logotype on the box that looks like a brand name is EEP. I have no idea what it means. There are no markings on the bottom of the container that would tell anything more about the puzzle.

I am selling this cube. It's extremely rare, and it's very expensive. Contact me if you're interested.
