YJ ZhiSu 4x4 Mini (Magnetic, Ball-Core, UV Coated) - 5.6cm is the industry's first mini 4x4 that performs well! The ZhiSu is incredibly impressive and feels just like a mini MGC 4x4. The factory-installed magnets feel great and have the same moderate strength throughout the inner and outer layers, and the corner cutting is incredible at almost 45 degrees, which is substantially more than a standard 4x4.

Ball-Core

• Corner-to-core magnets for a better, more controllable turning feel
  
• Auto-alignment
• Increased stability

UV Coating

• Super glossy plastic, high grip
