MoYu MFJS MeiLong 13x13 V3 - 8 Magnet Ball-Core is a compact, magnetic 13x13x13 Rubik's-style puzzle for fans of large cubes. Its 184-magnet positioning system includes an eight-magnet Ball-Core, combining magnetic layer alignment with additional core stability. At only about 75 mm per side and roughly 310–315 g for the cube itself, it is considerably easier to handle than many older 13x13 designs.

Who it's for

For experienced cubers who already solve smaller big cubes such as 5x5, 7x7 and 9x9; for collectors looking for a modern 13-layer model; and for people who want added control on a challenging 13x13 solve. The magnetic system is especially useful when many narrow layers need to stay aligned.

Feel and control

• Magnetic positioning: the 184 magnets help layers settle into alignment, improving control and reducing accidental misalignment.
• Eight-magnet Ball-Core: magnetic interaction around the core supports stability and consistent turning.
• Compact build: approximately 75–75.5 mm wide with widened outer layers for a secure grip.
• Six-pillar integrated core: supports the mechanism across all six faces.
• Rounded inner geometry and anti-pop design: help reduce catches and keep the many small pieces in place.
• Adjustable screw-and-spring tension: lets you tune the turning feel. This is not a MagLev model.

Magnets and surface

This is the magnetic Ball-Core version, not the non-magnetic MeiLong 13x13 V3. Despite the name “8 Magnet Ball-Core”, the whole cube contains 184 magnets; eight of them are used in the Ball-Core system. The six-colour, stickerless plastic has a matte (frosted), non-UV finish and requires no colour stickers.
