5. Care and Maintenance
To ensure the longevity and cleanliness of your COGO MAN building set, follow these simple care instructions:
- Cleaning: Wipe the building blocks and assembled models with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic.
- Storage: Store the blocks in a clean, dry place away from direct sunlight and extreme temperatures to prevent warping or discoloration.
- Handling: While durable, avoid excessive force when assembling or disassembling pieces to prevent breakage.

If you encounter any issues with your building set, please refer to the following common solutions:
- Missing Pieces: Carefully check all packaging materials. If a piece is genuinely missing, please contact customer support as detailed in Section 8.
