Microwave your white melting wafers in a bowl, 30 seconds at a time, stirring until smooth.
Dip each Oreo into the melted chocolate using a fork. Tap off excess and place on a parchment-lined tray.
Refrigerate the dipped Oreos for 10–15 minutes until firm.
Use a blue edible marker to draw 3–4 horizontal lines across the cookie.
Use a red edible marker to draw 1 vertical line on the left side (like notebook paper).

Let the icing dry fully before stacking or packaging.
Store in an airtight container at room temp for up to a week.
