No two serving boards are alike, therefore wood and marble grain will vary with each board. See pictures for examples.
Avoid holding your serving board by the handle alone. This places the weight of the marble solely on the handle and could result in a broken board.
Both the marble and the wood surfaces of the serving board you are purchasing are susceptible to stains from the natural oils found in foods. Your board has been sealed with a food-safe penetrating marble sealer. This will help cut back on oil spots but will not prevent them entirely.
To clean your board, simply wipe down with a warm, damp dish towel or paper towel. This serving board is not dishwasher safe and should not be cleaned with dishwashing liquids.
