A sanitizing apparatus for writing utensils comprising a housing assembly and an ultraviolet and ozone generating assembly housed therein. The housing assembly comprises a top wall, a base and four walls. The first and second walls are perpendicularly disposed with respect to the third and fourth walls. The third and fourth walls are lateral walls. The housing assembly also comprises an angled wall that protrudes outwardly beyond the top wall and beyond the first wall defining a tray that terminates with a lip for preventing the writing utensil from falling off. A battery compartment is also housed within the housing assembly. The ultraviolet and ozone generating assembly radiates the writing utensil within the housing assembly with rays and ozone, to effectively sterilize bacteria and biological germs existing on the writing utensil. A visual indicator notifies a user when the ultraviolet and ozone generating assembly is operating.
