4. Assembly Instructions
Follow the step-by-step visual instructions provided in the included instruction sheet. The assembly process involves connecting the micro-sized blocks to form the Arc de Triomphe.
- Preparation: Open the package and carefully sort the nanoblock pieces by color and shape. This will make the assembly process easier.
- Foundation: Begin by constructing the base of the Arc de Triomphe as shown in the first steps of the instruction sheet. Ensure the foundation is stable.
- Layer by Layer: Proceed with building layer by layer, following the diagrams precisely. Pay close attention to the placement of each block, as nanoblocks are very small (minimum size 4x4mm).
- Archway Construction: Carefully assemble the archway sections, ensuring they align correctly to form the central opening.
- Detailing: Add the decorative elements and the top structure as indicated in the later steps.
- Completion: Once all blocks are placed, gently press down on the entire model to ensure all connections are secure.
Tip: Use tweezers (not included) for precise placement of smaller blocks if needed.

5. Display and Handling
Once assembled, your nanoblock Arc de Triomphe de l'Étoile is ready for display.
- Placement: Place the model on a flat, stable surface away from direct sunlight, excessive heat, or moisture.
- Handling: When moving the model, support it from the base to prevent accidental disassembly. Avoid dropping or applying excessive force.
- Interaction: While durable, nanoblock models are not designed for rough play. They are primarily for display and light handling.
6. Maintenance
To keep your nanoblock model looking its best:
- Cleaning: Dust the model regularly with a soft, dry brush or a can of compressed air.
- Deep Cleaning: For more thorough cleaning, gently wipe with a slightly damp cloth. Do not immerse the model in water or use harsh cleaning agents.
- Storage: If disassembling for storage, keep all blocks organized in a sealed container to prevent loss.
7. Troubleshooting
- Missing Pieces: If you believe pieces are missing, double-check the packaging and your work area. nanoblocks are very small and can be easily overlooked. If still missing, contact KAWADA customer support.
- Difficulty Assembling: Refer to the instruction sheet carefully. Ensure blocks are oriented correctly and pressed firmly into place. Sometimes, a small error in an earlier step can affect later assembly.
- Model Instability: Ensure all blocks are securely connected. If parts feel loose, gently press them together.
