Line a baking sheet with parchment paper and set aside.
Since white chocolate hardens so quickly, it's easiest to work in several batches: In a microwave safe bowl place 1/2 cup of white chocolate chips with 1/4 tablespoon vegetable oil in the microwave.
Microwave for 30 seconds, stir, and microwave for another 25 seconds. Stir until melted or return to the microwave for a little longer. Add more vegetable oil if needed.
Holding the cookie in one hand and holding a spoon in the other hand, spoon the melted chocolate over the top 2/3rds of the cookies.
Lightly tap the cookies on the edge of the bowl to get a nice even coating of chocolate. (Don't dip the cookie in the chocolate because the chocolate in the milano will mix with the white chocolate).
Place the dipped cookies on prepared baking sheet and allow to completely dry.
Repeat with remaining cookies.
Place all the leftover white chocolate (make sure it is still very melted -- place in microwave for another 15 seconds if needed) into a small plastic bag (or a frosting bag fitted with a #2 tip)
Cut the very edge corner off of the bag and then pipe the melted white chocolate over the cookies to form the "bandages" of the mummy.
Secure 2 sprinkle eyes on the wet chocolate.
