To use this puzzle, simply sit at a table and start arranging the pieces. For kids, start by showing them the numbers or animals on each piece. Let them enjoy fitting the pieces together. When it's done, you can flip it over and start again. As for maintenance, keep it in a dry place to prevent the wood from warping. Avoid getting it wet. If it gets dirty, you can gently wipe it with a dry cloth. Always supervise young children while they are playing with the puzzle to prevent them from putting the pieces in their mouths.
