The "Guo" prefix series is a group of three-no products that enter the market informally. They are all trial products, and different materials and structures will change at different times. As a country, there will be obvious differences in buying one after another. There are still two national teams, which are bold and innovative in structure. There are several generations of fully enclosed series. C claims to imitate the Rubik's cube, but many genuine Rubik's cube users find that the feel is very different. C also contains a rich series of products, so I won't go into details, but it is no problem to use it to screw the screws quickly. Last year, "Guojia" began to try to register a trademark, but the Guojia logo posted on the Rubik's Cube still has no registered trademark logo.

Tell me about your ever-changing demon. You said white. I have seen two models with different packages in the market. The use effect is still good. I didn't use the new one directly. After polishing and lubrication, it took 10 seconds to assemble easily. If anyone can't get up quickly, it's not a Rubik's cube.

Do you understand now? Country * is not a noun, but a synonym to distinguish various series of trial products, and it is not a trademark at present. What you bought is "Amazing Devil", which is as famous as "Electronic Music" and "Ghost Hand".
