We have developed a spring system called [FangMoWang Spring System]. We have obtained a patent for this. FangMoWang's unique nut, precision spring, and spring cap...these three components have created an unprecedented system. The spring strength on all sides can be easily adjusted to meet the user's requirements. [Fast & Smooth] The inside corners of the cube are slightly rounded, and the center piece (the legs at the center of the inside) is circular to achieve fast and smooth movement. A built-in spring increases the cube's flexibility and maneuverability. The anti-stick design eliminates the problem of getting stuck when rotating the cube, allowing for smooth operation. The grip is firm and not too tight. The cubes are pre-lubricated and final conditioned at the manufacturer. If you are aiming to break the record, please get it! [Stability and Safety] The new structure of anti-POP---excellent fault-tolerant performance---can avoid POP (disassembly) caused by high-speed rotation operation or operational errors. In order to prevent parts from falling or being damaged during rotation operation, 1mm of extra space is provided on the internal spring bearing.
