We recommend the brand of Chalk Markers we carry as they have been tested on our boards and most compatible with our signs. We cannot guarantee the quality of other brands of markers. Alternate brand recommended for our signs: is QUARTET Glo-write Markers. Results may vary from brand to brand.
***Our boards are like Dry-Erase Boards, and so like chalkboards or dry-erase boards, ghost lines or writing shadows may result but does not affect the functionality of the boards.
