Assembly Instructions
The Magnext Mag-Box utilizes innovative magnetic panels and interlocking construction. Follow these steps to assemble a basic cube structure:
- Connect Panels: Use the magnetic edges of the panels to connect them. The magnets will snap together, forming strong bonds.
- Insert Ball Bearings: Place the non-magnetic ball bearings into the designated corner slots of the connected panels. These act as connectors and pivot points.
- Add Building Bricks: Utilize the included building bricks to customize your creations. The panels are brick-compatible, allowing for integration with other building systems.

How to Play and Create
The Magnext Mag-Box encourages creative construction using the power of magnetism and traditional building bricks. Here are some ways to engage with your set:
- Geometrical Forms: Experiment with the magnetic panels to create various 2D and 3D geometrical shapes beyond the basic cube.
- Custom Designs: Use the brick-compatible panels to integrate your existing building bricks, adding new dimensions and details to your magnetic structures.
- Expand Your Collection: Combine the Mag-Box with other Magnext sets for larger and more complex creations.
- Educational Activities: The set can be used for educational activities to develop creativity and problem-solving skills.

Care and Maintenance
- Cleaning: Wipe the magnetic panels and bricks with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the components in a dry place away from direct sunlight and extreme temperatures to preserve material integrity and magnetic strength.
- Handling: While durable, avoid excessive force or dropping the components from significant heights to prevent damage.
Troubleshooting
- Magnets Not Holding: Ensure panels are aligned correctly. Magnets have polarity; if two panels repel, try rotating one 180 degrees.
- Bricks Not Attaching: Verify that the building bricks are compatible with the studs on the Magnext panels. Apply gentle, even pressure when attaching.
- Missing Parts: If any parts are missing from a new, unopened package, please contact customer support.
