1. Use frame protection: putting the signature chessboard into the frame can protect the chessboard from damage and pollution. The frame can be made of wood, metal or plastic, depending on personal preference and actual needs.

2. Avoid direct sunlight: The signature chessboard should avoid direct sunlight, because prolonged exposure to sunlight will lead to fading of the signature or deformation of the chessboard. Store the chessboard in a cool and dry place to avoid direct sunlight.
