In a bowl, heat the milk chocolate for 15 seconds and stir, heat for another 10 seconds and stir again. Repeat until chocolate is completely melted.
Dip one pretzel at a time in the melted chocolate until completely covered. Lift the pretzel with a fork and let the excess chocolate drip. Put over a baking sheet lined with wax paper. Repeat the process until all the pretzels are done and refrigerate for 20 minutes
In a small bowl, melt the white chocolate, the same as the milk chocolate, stirring every 10-15 seconds. Pipe or drizzle the white chocolate over the cooled pretzels, and let the white chocolate set before moving
