- Unpack Components: Carefully open the packaging and lay out all the nanoblock pieces on a clean, flat, and well-lit surface. Ensure no pieces are lost.
- Review Instructions: Before starting, thoroughly read through the entire instruction booklet. Familiarize yourself with the block types and the assembly sequence.
- Follow Step-by-Step Diagrams: Each step in the instruction booklet will show a diagram indicating which blocks to use and where to place them. Pay close attention to the orientation and color of each block.
- Secure Connections: Press blocks firmly together to ensure a secure connection. The small size of the blocks requires precision.
- Patience is Key: Due to the intricate nature of nanoblock models, assembly requires patience and focus. Take breaks if needed.

Display and Care
Once assembled, your nanoblock Koala is designed for display and collection. To ensure its longevity and appearance:
- Stable Surface: Place the assembled model on a flat, stable surface to prevent accidental falls.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight may cause colors to fade over time.
- Keep Away from Dust: Display in an area with minimal dust accumulation.
- Handle with Care: While durable, the small connections can break if excessive force is applied. Handle the model gently.
Maintenance and Cleaning
To keep your nanoblock Koala model clean and well-maintained:
- Dusting: Use a soft, dry brush (like a clean makeup brush or a soft-bristled toothbrush) to gently remove dust from the model. Compressed air can also be used carefully.
- Spot Cleaning: For stubborn dirt, lightly dampen a cotton swab with water and gently wipe the affected area. Avoid using harsh chemicals or abrasive cleaners.
- Avoid Soaking: Do not submerge the model in water, as this may loosen connections or damage the plastic over time.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Missing pieces | Pieces may be very small and easily overlooked; manufacturing error. | Carefully re-check the packaging and work surface. If pieces are genuinely missing, contact nanoblock customer support (see Support section). |
| Difficulty connecting blocks | Incorrect block orientation; insufficient force; warped block. | Ensure blocks are correctly oriented as per instructions. Apply firm, even pressure. If a block appears warped, try another similar piece if available, or contact support. |
| Model is unstable | Blocks not fully pressed together; incorrect assembly step. | Review previous steps in the instructions to ensure all connections are secure and all blocks are placed correctly. |
