Please ensure to only write on the smooth side of the board with a pen that has been suggested (chalk marker or whiteboard marker). The smooth side is the side that is not backwards when looking at the board. If writing onto the raised side that has been lasered, any type of pen will permanently seep into the acrylic and it will not be able to be removed. This is your responsibility and the product will not be replaced if this happens.
To avoid ghosting on the acrylic board, please wash off or wipe any writing within 12 hours. Ensure to only write on the correct side. Do not write over the top of the white lasered writing as this will not be able to be removed.
