4.1 Understanding nanoblock Pieces
nanoblocks are miniature building blocks. The smallest block measures 4x4x5mm. This small size allows for intricate details in your creations.

5. Operating Instructions (Building)
Follow these general guidelines for building with nanoblocks:
- Review Instructions: Before starting, carefully examine the included instruction sheet for the model you wish to build. Identify the required block types and colors.
- Sort Blocks: For easier assembly, sort the blocks by color and type. This can significantly speed up the building process.
- Connect Blocks: Align the studs on one block with the holes on another. Apply gentle, even pressure to snap them together. The small size of nanoblocks requires precision.
- Use Tweezers (Optional): For very small or hard-to-reach areas, a pair of fine-tipped tweezers (not included) can be helpful for placing blocks accurately.
- Disassembly: To separate blocks, gently twist them apart or use a block separator tool if available (not included). Avoid excessive force to prevent damage.
- Creative Building: Once you are familiar with the basic building techniques, feel free to experiment and create your own original designs.

6. Maintenance
- Cleaning: To clean nanoblocks, wipe them gently with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store blocks in their original container or a suitable storage box to prevent loss and keep them free from dust.
- Avoid Heat: Do not expose blocks to high temperatures, as this can cause warping or melting.
7. Troubleshooting
- Blocks Not Connecting: Ensure the studs and holes are perfectly aligned. Apply firm, even pressure. If blocks are still difficult to connect, check for any debris in the holes or on the studs.
- Model Instability: If your model feels unstable, double-check the assembly steps. Ensure all blocks are fully connected and that the base is solid. Sometimes, a slight misalignment can affect overall stability.
- Missing Pieces: While rare, if you believe pieces are missing, carefully re-check the packaging and your building area. If pieces are genuinely missing, contact KAWADA customer support.
