Maintenance
To maintain the quality and longevity of your LEGO Iconic Chess Set, follow these guidelines:

- Handling: Handle the assembled pieces and board with care to prevent accidental disassembly.
Troubleshooting
If you encounter any issues with your LEGO Iconic Chess Set, consider the following:
- Missing Pieces: Carefully check all packaging materials. If a piece is genuinely missing, contact LEGO Customer Service for assistance.
