When handling your puzzle, please follow these rules:

Do not wet the Puzzle with water*, because the wood easily absorbs moisture and can be deformed.
* wipe them only with dry paper napkins (without detergents/cleaning agents)

Don't let children under the recommended age play with the puzzle.

If the parts are assembled correctly, they fit together easily, and you don't need to use brute force to connect them.

If you want to draw on the backside of the puzzle, the best way to do this is to use acrylic paint, since it looks great on wood and does not break its structure. You can also use any type of pencil.
