I wanted to clarify some information on the Expo brand Markers that are required to use with the Drawing Board.
SANFORD the company who makes the EXPO brand markers used to call our preferred marker EXPO 2. It uses alcohol in them as the solvent. Now they have changed the name to EXPO LOW ODOR. This is the same marker as the old Expo 2...just a new name. They are fading out the Expo 2 brand name so you might still find them around.
EXPO (ORIGINAL INK) These are also dry erase but they have keytone in them as a solvent and will stain our plastic we use on the drawing board. NEVER use these plain EXPO markers (original ink)...they will stain the board.
