Vintage Sanford Expo Markers potent smelly metal orange green yellow black smell All work but may have some issues/color bleeding. Black marker is a plastic casing and the rest are metal casing. Black marker tip has a bit of fraying. Orange marker ink is faded/not bright like it should be. Marks/wear/paint wear to casings as shown. All are very potent smelling. See all pics.
