- Approximately 1390 plastic micro building blocks.

4. Assembly Instructions
Follow these steps carefully to assemble your Black and White Cat model:
- Preparation: Unpack all pieces and organize them by color or shape if desired. Ensure you have a clean, well-lit workspace. Consider using a tray or mat to prevent small pieces from rolling away.
- Layer-by-Layer Construction: The model is built layer by layer. Attach one layer at a time, carefully identifying the correct fitting points for each piece as indicated in the instruction manual.
- Patience is Key: The initial layers of the model can be the most challenging due to the small size and intricate connections. Take your time and double-check each step. The assembly process will become significantly easier once the first few layers are securely in place.
- Refer to Images: Constantly refer to the provided images in the instruction manual to ensure correct placement and orientation of the blocks.

5. Maintenance
To ensure the longevity and appearance of your Larcele Micro Building Blocks model:
- Cleaning: Gently wipe the assembled model with a soft, dry cloth to remove dust. For more stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the model in a stable location away from direct sunlight and extreme temperatures to prevent discoloration or material degradation.
- Handling: Handle the assembled model with care to avoid accidental disassembly, especially if it is frequently moved.
6. Troubleshooting
If you encounter any issues during assembly or with your product, consider the following:
- Missing Pieces: Carefully check all packaging materials. If pieces are genuinely missing, please contact Larcele customer support for assistance.
- Difficulty Assembling: Re-examine the instruction manual closely. Sometimes a small detail or orientation can be missed. Take a break and return to it with fresh eyes. Ensure you are using the correct pieces for each step.
- Loose Connections: Ensure each block is firmly pressed into place. Micro blocks require a snug fit.
