These are the most cost effective types of writing surfaces as the top layer of the writing board is Laminated Melamine sheet which can be used as a white Board for marker writing. Laminated sheet for chalk board is also available in Green and Black color. Laminated surface is non magnetic in nature and can be erased with the help of a duster. Life of laminated boards is less as compared to other available writing boards as the surface can easily be scratched & damaged with used chalks or markers.
