- Workspace Preparation: Choose a clean, well-lit, and stable surface for assembly. A large area is recommended due to the number of pieces.
- Sorting (Optional but Recommended): For easier assembly, sort the nanoblocks by color and size. This can significantly reduce building time and frustration.

Maintenance
- Cleaning: To clean the assembled model, use a soft, dry brush or a can of compressed air to remove dust. Avoid using water or chemical cleaners, as these may damage the blocks or cause discoloration.
- Storage: Store the assembled model or unbuilt blocks in a cool, dry place away from direct sunlight to prevent material degradation or color fading. Keep loose blocks in their original packaging or sealed containers to prevent loss.
- Handling: Handle the completed model with care to avoid accidental disassembly.
Troubleshooting
- Missing Pieces:
- If you discover missing pieces, double-check all packaging and the surrounding workspace. If pieces are still missing, contact KAWADA customer support with details of the missing components.
- Difficulty with Assembly:
- Review the instruction manual carefully, paying close attention to the diagrams. Ensure blocks are oriented correctly and fully pressed into place. Sometimes, a small error in an earlier step can affect later assembly. Re-examine previous steps if necessary.
- Model Instability:
- Ensure all blocks are firmly connected. Apply gentle, even pressure when joining blocks. If a section feels unstable, re-check the connections in that area.
