The listing, Crayola Washable Window Mega Markers-4/Pkg has ended.
CRAYOLA-Washable Window Mega Markers in Blue Pink Yellow and Green. These markers make it easy to decorate windows glass mirrors Mylar and more. Window Mega markers cover more area and contain more ink than regular Crayola Window markers. That is because of the extra wide nib and greater ink supply-almost 3 times more! Non toxic. Conforms to ASTM D4236. I don't know if they were ever even used or not. Very good condition in original box.
